How to round up in Javascript

This function takes a number as an argument and returns the smallest integer greater than or equal to that number.

Here's an example:

let myNumber = 4.8;
let roundedNumber = Math.ceil(myNumber);

console.log(roundedNumber); // Output: 5

In this example, the Math.ceil() function is used to round up the number 4.8 to the nearest whole number, which is 5.
