How to create an arrow function in JavaScript?

Question

Gulshan Negi · Answer

Well, here is a simple example of how to create an arrow function in JS.

// Arrow function with no parameters
const greet = () => {
return 'Hello!';
};

// Arrow function with one parameter
const square = x => {
return x * x;
};

// Arrow function with multiple parameters
const add = (a, b) => {
return a + b;
};

Thanks

Creating an arrow function that returns a random number between 1 and 100 involves using the Math.random() method, which generates a random floating-point number between 0 (inclusive) and 1 (exclusive). You can then multiply this value by 100 to get a random number between 0 and 99, and finally, add 1 to shift the range to 1-100. Here's the explanation followed by the code:

Explanation:

Math.random(): This method generates a random floating-point number between 0 (inclusive) and 1 (exclusive).
Math.random() * 100: Multiply the random value by 100 to get a random floating-point number between 0 (inclusive) and 99 (exclusive).
Math.floor(Math.random() * 100): Use Math.floor() to round down the random value to the nearest integer, resulting in a random integer between 0 and 99.
Math.floor(Math.random() * 100) + 1: Finally, add 1 to the result to shift the range to 1-100.

Now, let's write the code:

const getRandomNumber = () => Math.floor(Math.random() * 100) + 1;

// Usage:
const randomNum = getRandomNumber();
console.log(randomNum); // This will print a random number between 1 and 100.

In this code:

We define an arrow function called getRandomNumber.
Inside the function, we use the Math.random() method to generate a random floating-point number between 0 and 1, and then we apply the necessary calculations to obtain a random integer between 1 and 100.
We call the getRandomNumber function to get a random number and store it in the randomNum variable.
Finally, we log the random number to the console.
