I have a textInput. When i click on the textInput, i want "Search Icon" to be passive, but when i dont click on the textInput, i want "Search Icon" to be active,

Its strangely not doing what I want. As I look at my code, it looks correct, but i must have something wrong because it doesnt work as i wanted.(not giving an error tho)

App.js

As we may know, var keyword defines a variable globally, or locally to an entire function regardless of block scope. So the below code will log 5 times with the same value.

I have three data frames. The first data frame df_1 is the baseline data frame, the rest of the data frames contains information that I want to add to the matching observations of df_1 The problem is that the observations don't have the same names I have a fourth data frame with the corresponding name on each variable. I want to recognize those values that have matching observations in the rest of the data frames to get a single data frame with all the observations.

I have a progress bar like shown in the picture below, that adds a certain amount of Image.fillAmount after each level is completed. How can i save that fill amount, do i store it in another variable, using Player Prefs or what? To try to explain:

Level 1 is completed it adds one star

Level 2 is completed it adds one more star etc etc:

Here is part of my code in LevelControl that adds fillAmount:

Please do correct me if I'm wrong about anything:

The JS runtime engine agents are driven by an event loop, which collects any user and other events, enqueuing tasks to handle each callback.

The event loop runs continuously and has the following thought process:

• Is the execution context stack (commonly referred to as the call stack) empty?
• If it is, then insert any microtasks in the microtask queue (or job queue) into the call stack. Keep doing this until the microtask queue is empty.
• If microtask queue is empty, then insert the oldest task from the task queue (or callback queue) into the call stack

So there are two key differences b/w how tasks and microtasks are handled:

• Microtasks (e.g. promises use microtask queue to run their callbacks) are prioritised over tasks (e.g. callbacks from othe web APIs such as setTimeout)
• Additionally, all microtasks are completed before any other event handling or rendering or any other task takes place. Thus, the application environment is basically the same between microtasks.

Promises were introduced in ES6 2015. I assume the microtask queue was also introduced in ES6.

What was the motivation for introducing the microtask queue? Why not just keep using the task queue for promises as well?

Update #1 - I'm looking for a definite historical reason(s) for this change to the spec - i.e. what was the problem it was designed to solve, rather than an opinionated answer about the benefits of the microtask queue.

So basically i have reducer with state called isHamburgerIsOpen. This is for to check if hamburger icon is clicked i want to blur my background:

Get the same problem developing my react app. So I have import JQuery using such a command

I'm a react beginner, so I don't know much, I tried to invoke a function where the JWT token is taken from the Local Storage and compared with that of from the backend, by sending an Axios request so that if I get a 200 response it means I can redirect it to another page, and while it is an error I can request the user to login. (please note that this is not a professional project but I need your help very much, guys)

The problem that I am facing is is the way that I set the OnClick in the cart button is correct? and how can I fix the React Hook Error that comes while maintaining this as a class? Unhandled Rejection (Error): Invalid hook call. Hooks can only be called inside of the body of a function component

I want to know what happens in this code-snippet with the chain of .thens with regards to the stack, the WebAPI section and the micro-task queue. I tried it in Loupe but it didn't seem to register the .thens.
