Difference Between Arrow Function And Normal Function Javascript
In JavaScript, arrow functions and normal functions are both used to define functions, but they have some key differences. Arrow functions have a more concise syntax and do not bind their own `this` or `arguments` values, whereas normal functions have their own `this` and `arguments` values bound. Arrow functions are also more suitable for quick, simple one-liner functions or functions that do not require the use of `this`. Normal functions, on the other hand, are versatile and can be used in a wider range of situations, such as constructors, methods, and callback functions where the context (`this`) matters. Additionally, arrow functions do not have their own `prototype` or `constructor` properties, whereas normal functions do.

1 - Arrow functions in JavaScript:
Arrow functions are a more concise way to write functions in JavaScript.
2) Normal functions in JavaScript:
Normal functions are the traditional way of defining functions in JavaScript.
3) Arrow functions:
Have a more compact syntax compared to normal functions.
4) Normal functions:
Require the use of the `function` keyword to define a function.
5) Arrow functions:
Have an implicit return if the function body consists of a single expression.
6) Normal functions:
Require the use of curly braces and the `return` keyword for returning values from the function.
7) Arrow functions:
Do not have their own `this` context, lexically capturing the `this` value of the enclosing context.
8) Normal functions:
Have their own `this` context, which can be affected by how the function is called.
9) Arrow functions:

Are especially useful for short, single line functions.
10) Normal functions:
Are typically used for more complex functions that require multiple lines of code.
11) Arrow functions:
Cannot be used as constructors and do not have a `prototype` property.
12) Normal functions:
Can be used as constructors to create instances of objects, and have a `prototype` property.
13) Arrow functions:
Are generally preferred for callbacks and event handlers due to their concise syntax.
14) Normal functions:
Are useful for more complex logic that requires multiple statements and control flow.
15) Arrow functions:
Cannot change their `this` context using methods like `bind`, `call`, or `apply`.
16) Normal functions:
Allow you to explicitly set the `this` context using methods like `bind`, `call`, or `apply`.
