String Objects – Length

jumbled string

Strings are primitive JavaScript objects. Since they are objects, we can tap into some built-in methods to make string manipulation easier. So over the next several posts, I want to delve into a few of these more helpful methods.

Today, I want to cover the length property. The length property allows you to count the number of characters in a string. Let’s look at an example…

var myString = "Hello World!"; // Simple string object
myString.length; // Should respond with the value of 12

Cool, huh? Now I know what you may be thinking, “Why not just count that there are twelve characters in the string variable?” You could do that as this one is a simple example, but what if I asked you how many characters are in the Declaration of independence? Aah…not so easy now huh?

// Variable containing the text from the Declaration of independence
// Truncated for the sake of space within blog post
var declarationIndependence = "Declaration of Independence..."; // In reality contains entire text

The result of the output of console.log(declarationIndependence.length); would be – 8142…much easier than counting by hand!

Happy Coding!
