round a number to the nearest integer in javascript

To round a number to the nearest integer in JavaScript, you can use the Math.round() method. This method rounds a number to the nearest integer. Here's an example:

index.tsx
let num = 4.6;
let roundedNum = Math.round(num);
console.log(roundedNum); // output: 5
87 chars
4 lines

In this example, we first initialize a variable num with the value 4.6. We then use the Math.round() method to round num to the nearest integer and store the result in a new variable called roundedNum. Finally, we log the value of roundedNum to the console, which will output 5.

Note that the Math.round() method also rounds up if the decimal value is .5 or higher, and rounds down if it's lower than .5.
