Lesson Overview

Welcome! In this lesson, we'll delve into the basic string manipulation features of JavaScript, which include string tokenization, string concatenation, trimming of whitespace from strings, and type conversion operations.

Tokenizing a String in JavaScript

In JavaScript, we can use the split method from the String class to tokenize a string, essentially splitting it into smaller parts or 'tokens'.

We start by declaring a string variable sentence containing the text "JavaScript is an amazing language!". On the second line, we use the split method with a space character " " as the delimiter. This method splits the sentence every time it encounters a space and returns an array of substrings or tokens. In this case, the resulting tokens array will contain ["JavaScript", "is", "an", "amazing", "language!"]. We then use the forEach method to iterate over each element (token) in the tokens array. The arrow function is executed for each token, printing each word to the console, one per line.
