React: How can I get the closest number in tens, hundreds, thousands... of a given number?

For some calculations, I need to get the closest number in tens, hundreds, thousands...etc of a given number. Examples:

1 becomes 10
3 becomes 10
15 becomes 20
36 becomes 40
105 becomes 110
1009 becomes 1010
... etc

Thanks in advance!

Revansiddh answer is really nice, only to 'fullier' answer the question:

function roundOff(num, precision = 10){
   return (precision - (num%precision)) + num
}
console.log("round off of 1009",roundOff(1049))
console.log("round off of 105",roundOff(1049, 100))
console.log("round off of 36",roundOff(1049, 1000))

You can do this.

let i = 105;
let result = (parseInt(i/10, 10)+1)*10;  
console.log(result);
