Arrow function

Arrow function is one of the features introduced in the ES6 version of JavaScript. It allows you to create functions in a cleaner way compared to regular functions. For example,

you can define a simple arrow function as follows:

const greet = () => {
    console.log("Hello!");
};

greet(); // Output: Hello!

In this example, the arrow function greet does not take any parameters and simply logs “Hello!” to the console.

Here’s an example of an arrow function with a parameter:

const square = (num) => {
    return num * num;
};

console.log(square(5)); // Output: 25

The arrow function square takes a num parameter, multiplies it by itself, and returns the result.
