How can you convert a number to a string in JavaScript?

In JavaScript, you can convert a number to a string using the `toString()` method or by using string concatenation. Here are both methods:

1. Using `toString()` Method:

   The `toString()` method is available on number objects, and it converts a number to its string representation.

   let number = 42;

   let stringRepresentation = number.toString();

   console.log(stringRepresentation);  // Outputs: "42"

You can also specify the base (radix) as an argument to the `toString()` method for numbers in bases other than 10 (e.g., binary, hexadecimal).

 

   let binaryNumber = 1010;

   let binaryString = binaryNumber.toString(2);

   console.log(binaryString);  // Outputs: "1010"

2. Using String Concatenation:

   You can also convert a number to a string by concatenating it with an empty string (`''`).

   let number = 123;

   let stringRepresentation = number + '';

   console.log(stringRepresentation);  // Outputs: "123"

This works because the `+` operator is overloaded in JavaScript, and when used with a string, it performs string concatenation.

Choose the method that best fits your specific requirements. The `toString()` method provides more control over the conversion process, especially when dealing with different bases, while string concatenation is a simple and concise way to convert a number to a string in most cases.
