How to count the trailing zeros in a binary number using JavaScript

Answer 1

function countTrailingZeros(n) {
    let binaryStr = n.toString(2); // Convert to binary string
    let trimmedStr = binaryStr.replace(/0+$/, ''); // Remove trailing zeros
    
    return binaryStr.length - trimmedStr.length;
}


let number = 80; // binary: 1010000

console.log("Number of Trailing Zeros:", countTrailingZeros(number));




/*
run:

Number of Trailing Zeros: 4

*/
