Wyatt is a Java & Spring based cryptocurrency trading bot that uses the public Binance API. It is run by providing it with API keys generated at binance.com (Also provide Wyatt with Twitter API keys if tweet alerts are desired). The bot then will pull recent trade candlestick data for the last 125 hours (5.2 days) and calculate a target price. If the target price is above the current price, a sell is executed and a buy back is placed. If not, Wyatt will wait 25 seconds before repeating the prediction/trading process.

                                                                                  I can already group the list by first character of last name:

                                                                                  I'm taking a JS course and right now we're covering Prototypes. My question has to do with the prototype object.

                                                                                  Here's the code sample:

                                                                                  class Pet {
                                                                                      constructor(name, age) {
                                                                                          this.name = name;
                                                                                          this.age = age;
                                                                                      }
                                                                                      eat() {
                                                                                          return `${this.name} is eating!`
                                                                                      }
                                                                                  }
                                                                                  
                                                                                  class Dog extends Pet {

                                                                                  const wyatt = new Dog("Wyatt", 13);
                                                                                  

                                                                                  If I type in the console: wyatt.eat()

                                                                                  (1) The console will look for the eat method on the Dog prototype. If it finds it, it'll run the method.

                                                                                  (2) If it doesn't find it there it will look at the Pet prototype for it, courtesy of the extends keyword.

                                                                                  (3) Now if it doesn't find it there, the console will look for it on the "Object Prototype" (the way the tutor formulated it).

                                                                                  I get all of the above and that a class instance has a prototype template it refers to, and possibly others. The confusing part for me is specifically at step (3), what is the prototype here? Is it looking on the global object? Would that be the window object? This part is still a bit shaky for me.

                                                                                  Many thanks.

                                                                                  While what you wrote is not wrong, the realty is simpler (IMO).

                                                                                  If you try to access a property on an object, the engine will first check whether the object itself (in your case wyatt) has that property. If not, it will look at the object's prototype (which is also an object) and repeat those steps until it finds the property or until an object doesn't have a prototype anymore. That's really all that is to it.

                                                                                  An object can only have one prototype. You can think of it as it being an "internal" property that is assigned a reference to another object.

                                                                                  I guess the next question is, how is a prototype assigned to an object? You already know one way: the extends keyword.
                                                                                  Maybe the point that you are missing is that the default prototype of an object is Object.prototype:

                                                                                  console.log(Object.prototype === Object.getPrototypeOf({}));

                                                                                  Object.prototype however doesn't have a prototype:

                                                                                  console.log(Object.getPrototypeOf(Object.prototype));

                                                                                  That's where the prototype chain ends.

                                                                                  So to summarize, the engine doesn't think "oh I have to look at Object.prototype now", it just knows to look at the object's prototype, whatever that may be. It's just the case that Object.prototype is the default prototype for "normal" objects.

                                                                                  Source https://stackoverflow.com/questions/67486839

                                                                                  Your problem comes from an unidentified variable. Fortunatly that is very easy to fix. All you have to do is define command before you call it.

                                                                                  For this we'll splice the message content into two parts. The command and any arguments that may be included like mentions or other words. We do that with:

                                                                                  const args = message.content.slice(prefix.length).split(/ +/);
                                                                                  const command = args.shift().toLowerCase();
                                                                                  

                                                                                  Note: The args constant is an array.

                                                                                  Which would make your entire onMessage event look like this:

                                                                                  client.on('message', message => {
                                                                                      const prefix = "!";
                                                                                      const args = message.content.slice(prefix.length).split(/ +/);
                                                                                      const command = args.shift().toLowerCase();

                                                                                  I am trying to take a random name from a list and then once it has been printed, I want to remove it from that list so that it isn't used ever again. I want to use the pop method but I'm not sure how to take a random name from the list since the pop method (to my knowledge) only accepts integers.

If I just want to do a one-to-one transfer if I know that the order of the items in the dictionaries are the same, how could I do so?

Thank you.

                                                                                  Instead of storing stats as a state object, you could use a getter which will be reactive to your reservation state.

                                                                                  getters: {

I want the table to scroll at least and have the form fields be actually visible to the eye. Specifically you can see this in the innings pitched.

                                                                                  React: Mutate nested states once
                                                                                  Asked 2020-Aug-10 at 06:32

                                                                                  So in typical programming scenarios, if you mutate an object, it mutates the object everywhere. However, in React, since states are immutable and only mutable through each's set*, if states are nested in each other, like the scenario shown below, only the currentMember's name will change, and not the version of currentMember in currentTeam, or teams. I'd have to go through each and mutate them one by one, which is cumbersome.

                                                                                  What would be the best way to mutate multiple states at once, or achieve a similar effect? I've done so by indexing, but it's more cumbersome to work with, and i didnt know if there were a textbook hook that fixes this.

                                                                                  As mentioned, you are making things a bit complicated by using state this way. You should have one base state that contains all of the teams, then reference the bits that are important to you by index.

                                                                                  For example, your teams state is fine as is. Your currentTeam and currentMember states should be indexes or some other reference to the state within teams you want to map to.

                                                                                  So, in specific terms, I'd change the format of your code here like so (forgive me as I don't write TypeScript, so I'm going to straight vanilla javascript to avoid making typos):

                                                                                  You might also want to consider confining this in a reducer, with a specific action containing the team id index, and member id index to make this quite a bit more composable.
