Data Types in JavaScript

The video tutorial introduces JavaScript data types, dividing them into primitive and reference types. Primitive types include strings, numbers, booleans, null, undefined, and symbols, while reference types encompass objects, arrays, and functions. The tutorial explains how JavaScript is dynamically typed, allowing variables to hold different types without errors. It also touches on TypeScript, which adds static typing to JavaScript. Practical coding examples demonstrate the use of the typeof operator to identify data types.
