JavaScript(JS) math method - clz32

The clz32 method in JavaScript's Math object returns the number of leading zero bits in the 32-bit binary representation of an integer.

The clz32 method takes one argument, which is the integer whose leading zero bits need to be counted. If the argument is not a number, it will be converted to one before the calculation. If the argument is NaN or outside the range of -2147483648 to 2147483647, NaN will be returned.

Here's an example usage:

const x = 7; // binary representation: 00000000000000000000000000000111
const clzX = Math.clz32(x);
console.log(clzX); // 29

In the above example, the Math.clz32 method is used to count the number of leading zero bits in the binary representation of the integer 7. The result, which is 29, is then logged to the console. Note that the binary representation of 7 is 00000000000000000000000000000111. There are 29 leading zeros in this binary representation.
