There are 3 approaches one can take to start React journey
➊ Complete JavaScript. Then, start React.
➋ Learn the essentials of JavaScript. Then, start React. Finally, learn advanced JavaScript.
➌ Start React. Learn JavaScript alongside.
JavaScript First, Then React?
Or,
JavaScript ✛ React?

➊ Complete JavaScript. Then, start React.

➌ Start React. Learn JavaScript alongside.
⬘ JavaScript is a language while React is one JavaScript-based library.
⬗ Looking at the popularity of React, few people directly start learning React without much/prior knowledge of JavaScript. Is this a good idea?
⬖ We will discuss those essential concepts in this thread.

25 powerful methods in JavaScript

It's frequently used in hooks esp. useState()
Example:
⇥ const [fruits, setFruits] = useState([]);

Array Destructure in JavaScript

\u2727 Explained like to a 10-years old

There are so many use cases. One of the place where we frequently spread an array is adding/updating/removing an item from the state.
Example:
Add an item to the starting of Array
⇥ let newArray = [itemToAdd, ...oldArray]

\U0001f499 Spread and Rest Parameter Operators (...) in JavaScript

Follow this \U0001f9f5 for the easiest and never-to-forget type explanation. Thank me later \U0001f61d

⬘ Properties are passed as an object parameter to our function component.
⬙ We can destructure it and, specify only those properties that we are going to use.
Example:
function MyComponent({name, address}) {
}
We may spread an object to pass those to a child component.
Example:
function MyComponent({name, address, ...rest}) {
return
}
➤ Untagged Template Literals
➤ Tagged Template Literals
This is used in a few stylesheet libraries.
➤ DOM API
Very important to learn how React handles DOM, events.
➤ Promise API
➤ async...await
These 2 are not hard stoppers though.
➤ Fetch API
Not a hard stopper. Learn for making API calls.
