To calculate x% of a number with JavaScript, we can divide x by 100 then multiply by the number we want to compute the percentage for.
For instance, we can write:
const x = 35.8
const result = (x / 100) * 10000;
console.log(result)
We assign the percentage number to x .
Then we divide that by 100 to get a decimal number with the fraction that we want to multiply the number with.
We multiply that by 10000 to get 35.8% of 10000 and assign that to result .
Therefore, result is 3580.
