String Concatenation
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)
