Hey there!
In this post and video, I'm going to explain how to use JavaScript length property with strings to find/count the number of characters in a string
When you use the length property with JavaScript strings it counts the number of characters you have in that string and returns a/an positive/integer number. That includes empty string, empty space.
Let's create 2 variables:
let firstName = 'Ada';
let myData = firstName.length; // returns 3
console.log(myData);
The way it's used is after or at the end of a variable with a .length like so firstName.length
If you check the typeof both variables the firstName is a string.
And myData is a number.
console.log(typeof firstName); // string
console.log(typeof myData); // number
If you are a visual person here's a video tutorial with code editor and whiteboard example.
Thanks for reading this.
