How to concatenate several strings in JavaScript?

JavaScript provides multiple methods to concatenate several strings. The most common approaches include using the + operator, template literals, Array.join(), and the concat() method.

Method 1: Using the + Operator

The simplest way to concatenate strings is using the + operator:

Method 2: Using Template Literals (ES6)

Template literals provide a cleaner syntax using backticks and ${} placeholders:

Method 3: Using Array.join()

When concatenating multiple strings with the same separator, Array.join() is very efficient:
