This video provides an overview of data types in JavaScript. We'll explore the different categories of data types, including primitive and non-primitive types. You'll learn about the six primitive data types: string, number, Boolean, undefined, null, and symbol (introduced in ES6).
We'll also cover non-primitive data types like objects, function, arrays and etc. You'll understand how objects allow you to store collections of data and key-value pairs, while arrays enable you to create ordered collections in the upcoming videos.
Throughout the video, you'll see plenty of code examples demonstrating how to work with string data type, perform type checking, and avoid common pitfalls. By the end, you'll have a solid grasp of JavaScript's data types specially string and be able to write more robust code.
1- String
The String data type represents a sequence of characters. Strings can be enclosed in single quotes ('), double quotes ("), or backticks (`).
