JavaScript percentage calculation functions
Multi tool use
$begingroup$
I am building a calculator and I'm aware of what these functions do.
What I basically want feedback on is: Do I need to comment this or is there sufficient information to ascertain its purpose:
function percentOfValue(percentage, of) {
return (percentage / 100) * of;
}
function whatPercentOfValue(small, large) {
return (small / large) * 100
}

Code level comments usually lose their context if not properly maintained. Using self descriptive variable names is a good choice. Appreciate your efforts in keeping the code highly readable.
First method, is trying to get the Percentage value, I would update the method definition to
getPercentOfValue(from, percentage).Second method, is trying to calculate percent rate, I would update the method definition to
getPercentRate(newValue, originalValue)to follow the terminology in formula.
