Append a number to a string in JavaScript

This post will discuss how to append a number to a string in JavaScript.

There are several methods to append a number to a string object in JavaScript. Here are some of the most common functions, along with some examples:

1. Using + or += operator

We can use the + operator to concatenate a number and a string. This operator converts the operands to strings if they are not already strings, and then joins them together. We can use this operator to append a number to a string by passing them as operands and converting the integer to a string implicitly. Here’s an example:

2. Using String.concat() function

Another way is to use the String.concat() function, which returns a new string that is the result of joining two or more strings. However, using the + operator is less error prone in case the first operand is not a string. Here’s an example:

3. Using template literals

Template literals are strings that allow embedded expressions and multi-line strings. We can use the template literals syntax to create a string that interpolates a number using the ${} notation. This syntax allows us to embed expressions inside a string literal, which is enclosed by backticks (`). For example, to append a number to a string, we can write:
