JavaScript Introductory Course - Variables: undefined | JavaScript | EN 🇺🇸
In this first lesson from the "variables" module of "JavaScript, Introductory Course", we're going to learn what is a variable and about the "undefined" primitive type.
Variables are pointers to memory that holds values, those values can be one of the seven primitive data types that the ECMAScript standard defines.
The `Undefined` type represents a variable that has not already been defined, meaning that it holds no value, but that emptiness is represented by the "undefined" primitive data type which is a property of the `global object`, which is a variable that's always available for you from everywhere.
