Summary  
This chapter explains how to concatenate strings in JavaScript using the + and += operators to build formatted text by combining words and adding spaces or punctuation.

General domain of usage  
Text manipulation

Let's explore some operations that you can perform with strings in JavaScript.

# Concatenation
Concatenation is the process of combining two strings. This operation is achieved using the `+` operator:

let wordOne = "Hello";
let wordTwo = "World";

console.log(wordOne + wordTwo);

You can see that concatenation creates a new string by combining two words.

> Note
>
> String concatenation does not automatically add spaces. You need to manually include spaces like `string1 + " " + string2`.

Let's create a nicely formatted string through concatenation:

let wordOne = "Hello";
let wordTwo = "World";

console.log(wordOne + ", " + wordTwo + "!");

# Concatenation with Assignment
The `+=` operator allows you to add text to a string-type variable:

let text = "Were";
text += "wolf";
text += "!";

console.log(text)
