How can I use modulo operator (%) in calculation of numbers for JavaScript projects?
回答1:
It's the remainder operator and is used to get the remainder after integer division. Lots of languages have it. For example:
10 % 3 // = 1 ; because 3 * 3 gets you 9, and 10 - 9 is 1.
Apparently it is not the same as the modulo operator entirely.
回答2:
That would be the modulo operator, which produces the remainder of the division of two numbers.
