Recursive Method
The recursive method for converting a number to binary involves repeatedly dividing the number by 2 and appending remainders to the binary representation using a recursive function.
Syntax:
function convertDecimalToBinary(decimalNumber) {
if (decimalNumber === 0) {
//code..
} else {
//code...
}
};
Example: In this example we are using the above-explained approach.
function convertDecimalToBinary(decimalNumber) {
if (decimalNumber === 0) {
// Base case: Return "0" if the number is 0
return "0";
} else {
// Recursive case: Divide the number by 2,
//append the remainder to the result of the recursive call
return convertDecimalToBinary(
Math.floor(decimalNumber / 2)) + (decimalNumber % 2);
}
}
const num1 = 10;
const result = convertDecimalToBinary(num1);
console.log(result);
Output
01010
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.
