To round a number to the nearest tenth in JavaScript, you can use the toFixed() method. Here is an example:

1
2
3
4
let num = 3.456;
let roundedNum = num.toFixed(1);

console.log(roundedNum); // Output: "3.5"


In this example, toFixed(1) rounds the number num to one decimal place, which is the nearest tenth. The resulting roundedNum is a string, so you may need to convert it back to a number using parseFloat() if you need to perform further calculations with it.
