Can you explain the meaning of the symbol >>=?

I'm confused about the meaning of >>= (I thought it was greater than or equal to as >=). Can you also explain what (times & 1) means in the code snippet below?

function repeat (string, times) {
var result = ''
while (times > 0) {
if (times & 1) result += string
times >>= 1
string += string
}
 return result
}

Answer №1

>>= represents a right-shift-and-assign operation in JavaScript. When used with >>= 1, it effectively performs integer division by 2.

& signifies a Bitwise AND operation in JavaScript. For example, using time & 1 can determine if a number is odd.
