相当于 JavaScript 中的 和 ？

Question

What's the equivalent of and in JS because I can't seem to find an answer

}else if (i % 3 & 5 === 0){
console.log('...')

Answer 1

A googling for "javascript AND operator" returns a first hit of http://www.w3schools.com/js/js_comparisons.asp which clearly explains the answer:

if (i % 3 && 5 === 0)

This is the answer you're looking for, but given how it's written, it might not give you the outcome you expect depending on execution.
