Convert a number to a string in JavaScript

In this article, we will convert a number to a string in Javascript.

In JavaScript, you can change any number into string format using the following methods:

Method 1: Using toString() Method

This method belongs to the Number.Prototype object. It takes an integer or a floating-point number and converts it into a string type.

Syntax:

num.toString();

Example: This example uses the toString() method to convert a number into a string.

Javascript

let a = 20;

console.log(a.toString());
console.log((50).toString());
console.log((60).toString());
console.log((7).toString(2)); // (7 in base 2, or binary)

Output

20
50
60
111

Method 2: Using the String() function

This method accepts an integer or floating-point number as a parameter and converts it into string type.

Syntax:

String(object);

Example: This example uses the String() function to convert a number into a string.

Javascript

let a = 30;

console.log(String(a));
console.log(String(52));
console.log(String(35.64));

Output

30
52
35.64

Note: It does not do any base conversations as .toString() does.

Method 3: Concatenating an Empty String

This is arguably one of the easiest ways to convert any integer or floating-point number into a string.

Syntax:

let variable_name =' ' + value;

Example: In this example, we will concatenate a number into a string and it gets converted to a string.

Javascript

let a = '' + 50;
console.log(a);

Output

50

Method 4: Using Template Strings

Injecting a number inside a String is also a valid way of parsing an Integer data type or Float data type.

Syntax:

let variable_name = '${value}';

Example: This example uses template strings to convert a number to a string.

Javascript

let num = 50;
let flt = 50.205;
let string = `${num}`;
let floatString = `${flt}`;
console.log(string);
console.log(floatString);

Output

50
50.205

Method 5: Using toLocaleString() Method

The toLocaleString() method converts a number into a string, using a local language format.

Example:

Javascript

let number = 92;
let numberString = number.toLocaleString();
console.log(numberString);

Output

92

Method 6: Using Lodash _.toString() Method

In this approach, we are using Lodash _.toString() method that convert the given value into the string only.

Example: This example shows the implementation of the above-explained approach.

Javascript

// Requiring the lodash library
const _ = require("lodash");

// Use of _.toString() method
console.log(_.toString(-0));

Output:

'-0'
