QUESTION
Codesandbox to the problem: https://codesandbox.io/s/serverless-thunder-6gj04?file=/src/store.js
I have the following store:
...ANSWER
Answered 2021-Mar-14 at 20:43As @Tholle said in the comment, you are only updating local variable, not actual object.
In simpler words this is what's happening inside your update function:
let updated = this.persons.find((p) => p.id === id);- you create local variableupdatedand assign some object (person) to itconst dummy_person = { first_name: 'foo', last_name: 'bar', id: 99 }- you create dummy object and assign it to localdummy_personconstantupdated = dummy_person- here you assigndummy_personvalue toupdatedvariable. Basically you only reassign value ofupdatedvariable, you are not changing the person-object, but only changing to what valueupdatedvariable points.
Sometimes people explain it with boxes, like imagine that updated is a box and at first you put person inside of it and then changed you mind and put dummy_person inside, but actual person wasn't changed.
So what can you do?
As @Tholle said, you can use splice to change persons array, it will basically throw away old person and insert new one.
Or if you actually want to update old person you could use Object.assign(updated, dummy_person)
Or you could use map (although it will reassign whole array, might be unnecessary sometimes):

I want random numbers so that I can advertise my app as, "Not giving anyone a disadvantage, fundamentally", I am making game about Quantum Uncertainty which is random, not just pseudo random, so I could do:
...ANSWER
Answered 2021-Jan-20 at 12:51Try using this module https://github.com/lmacken/quantumrandom
It gives you tools for interacting with The ANU Quantum Random Number Generator (qrng.anu.edu.au). So it makes your random absolutely random.

QUESTION
Using a basic example I'm attempting to randomly generate a bunch of Person (case class Person(name: String, age: Int) instances using this library for random data generation.
The problem I'm running into is when creating an Arbitrary that has bound limits for the age parameter as shown below.
...ANSWER
Answered 2020-Nov-13 at 19:38Even though an implicit value is seldom, if ever, referenced by name, it still needs one, what the language spec calls a "stable identifier."
Using _ as the variable name tells the compiler that it can forget about this value after it's been created.

QUESTION
I'd like to generate an arbitrary element of a parametrized case class, and found this library using ScalaCheck's gen to do it. This works for concrete types, but won't work for abstract ones; is there a way around this?
ANSWER
Answered 2019-Nov-12 at 20:15The random generator depends on an implicit value of type ClassTag to do its thing. However, A is not known until another trait or class actually extends Foo, so the compiler cannot provide the implicit parameter like it did with fooBound. Try keeping 'a' abstract and then overriding it in other classes, or passing A in as a ClassTag maybe? Look at the source code here to see https://github.com/DanielaSfregola/random-data-generator/blob/master/js/src/main/scala/com/danielasfregola/randomdatagenerator/RandomDataGenerator.scala
QUESTION
I have a piece of code that relies on the existence of an arbitrary element of a certain case class in order to operate on the class's fields. There are some options out there, and even though pretty much every Scala blog recommends not using null ever, it seems like not a terrible idea in type level programming (e.g. this answer: https://stackoverflow.com/a/4443972/1650448). However, this code directly casting null to a particular case class does not work and does not throw an error, and I'm interested in why.
ANSWER
Answered 2019-Nov-12 at 07:42Casting changes the compile-time type, not the runtime type. Pattern matching checks the runtime type. In fact, case class pattern matching even has an explicit check for null; see Why is there a `null` check in the implementation of the `unapply` method for case classes? (though that check doesn't affect your case since you're using a type pattern).
Also, even if it weren't for the pattern matching issue, you wouldn't be able to "operate on the class's fields" without getting a NullPointerException.

QUESTION
I'm trying to use lapply to each matrix of the list.
I want to apply sample function, using lapply.
Let's take an example. I generated the probability, which will be used for sample function. (Sorry for not optimizing.)
ANSWER
Answered 2019-Jul-08 at 08:08Without over-complicating it too much and continuing from your attempt, we can use sapply inside lapply. lapply would loop over each list whereas sapply would loop over every row in the list.
