In JavaScript, there are three ways of adding a string to the end of a string:
1. Using the addition operator: The addition operator (+) enables you to concatenate two strings. The following example shows you how to add a string to the end of a string:
let str = "I am learning"; console.log(str + " JavaScript."); //"I am learning JavaScript."
2. Using the concat() method: String provides the concat() method to append a string to the end of a string. The concat() method accepts one or more strings and returns a concatenated string.
Note: The concat() method does not modify the original string.
let str = "I";
console.log(str.concat(" am", " learning", " JavaScript.")); //"I am learning JavaScript."
3. Using template literal: ES6's template literal provides a new way of adding a string to the end of a string. Instead of single or double quotation marks, you enclose a string in backticks. In template literal, you use a dollar sign and curly braces for evaluating variables.
let str = "Mohit";
console.log(`${str} Natani`); //"Mohit Natani"
