Bit Manipulation Method
Bit manipulation is a technique where you manipulate individual bits of a number using bitwise operators. In the context of converting to binary, you can repeatedly extract the least significant bit (LSB) of the decimal number while shifting the number to the right.
Syntax:
for (; decimalNumber > 0;
decimalNumber = Math.floor(decimalNumber / 2)) {
binary = (decimalNumber % 2) + binary;
}
Example: In this example, The function decimalToBinary converts a decimal number to binary using a for loop. Bitwise operations shift the number’s bits, constructing the binary representation.
function decimalToBinary(decimalNumber) {
let binary = "";
for (; decimalNumber > 0; decimalNumber >>= 1) {
binary = (decimalNumber & 1) + binary;
}
return binary || "0";
}
const num1 = 32;
const Result = decimalToBinary(num1);
console.log(Result);
Output
100000
JavaScript Program to Convert a Number to Binary
We are going to learn the conversion of a number to binary by using JavaScript, Convert a number to binary in JavaScript refers to the process of converting a decimal number into its binary representation, which uses only the digits 0 and 1 to represent the value
Converting a number to binary in JavaScript involves transforming a decimal (base 10) number into its binary (base 2) representation.
For example:
(25)10 = (11001)2
(32)10= (100000)2
(8)10= (1000)2
There are several methods that can be used to Convert a number to binary in JavaScript, which are listed below:

- Approach 1: Using toString() method
- Approach 2: Bit Manipulation Method
- Approach 3: Recursive Method
- Approach 4: Using Array-Based Method
We will explore all the above methods along with their basic implementation with the help of examples.
