.split() Method

Use the .split() method when you want to split up a string into chunks. Let's say you wanted to split the sentence "The quick brown fox jumps over the lazy dog" into nine separate elements.

var str = "The quick brown fox jumps over the lazy dog.";

//splitting by whitespace
var strSplit = str.split(" ");

console.log(strSplit);

Output

[ 'The', 'quick', 'brown', 'fox', 'jumps', 'over', 'the', 'lazy', 'dog']

Now that you have the array, you can determine the number of words in a sentence. You could use this knowledge to grab a first name from a person's full name. In the next module, we'll use it to split a word into individual characters. Also, notice the empty " " in str.split? You can split a string using any character you want!
