JavaScript Reverse the order of the bits in a given integer

We are required to write a JavaScript program that reverses the order of the bits in a given integer.

For example −

56 -> 111000 after reverse 7 -> 111

Another example,

234 -> 11101010 after reverse 87 -> 1010111

Example

const num1 = 789; const num = 43 const reverseBits = (num = 1) => {    const str = num.toString(2);    const arr = str.split('').reverse();    const arrStr = arr.join('');    const reversedNum = parseInt(arrStr, 2);    return reversedNum; } console.log(reverseBits(num)); console.log(reverseBits(num1));

Output

And the output in the console will be −

53 675
