Why we create a arrow function ?

Arrow functions, introduced in ECMAScript 6, provide a concise syntax for writing anonymous functions in JavaScript. They offer a more streamlined and expressive way to define functions compared to traditional function expressions.

The syntax for arrow functions consists of parameters enclosed in parentheses (if there are any), followed by the arrow symbol =>, and then the function body enclosed in curly braces {} if it’s a block statement, or a single expression if it’s an expression-bodied arrow function.

Here’s an example of an arrow function in JavaScript:

Arrow functions inherit the this value from the enclosing lexical context, which means they don’t have their own this context. This behavior can be advantageous in certain situations, especially when dealing with callbacks or event handlers.

Additionally, arrow functions are concise and don’t require the function keyword, making the code more compact and readable, particularly for short, one-liner functions.

However, it’s important to note that arrow functions also have some limitations. They cannot be used as constructors and don’t have their own arguments object.

Overall, arrow functions are a powerful addition to JavaScript, offering a more elegant syntax and improved readability for defining functions.
