From string to binary??

Question

using JavaScript, I need to turn a string of numbers into a binary string.

all numbers less than <= 4 Are to be 0's, and numbers >= 5 Are to be 1's.

how do i write this function ()?

thanks in advance.

Answer 1

function isLarger(num, target) {
return num<target? 0:1;
}

alert(isLarger(4,5)); // return 0
alert(isLarger(5,5)); // return 1
