Math in javascript doesnt work the way i expected

Question

Im trying to use this equation to make a progress bar but when ever i try to divide a number with a percent it just gives me a error.

---

The equation:

/* jshint esversion: 6 */
let progress = (this.assetsComplete*100%)/((this.assets.length - this.exceptionLength)*40);

---

The only problem is when i do the division it gives an error is there a way to fix it?

i have tried adding extra parentheses but that didn't work.

Answer 1

Just take it without some percent calculation.

let progress = this.assetsComplete * 40 / (this.assets.length - this.exceptionLength);

The remainder operator % returns a rest of a dvision of a number by another number.
