In this video I explain 2 basic building blocks of JavaScript, which are Variables and Data Types.

I cover JavaScript’s 5 data types: Numbers, Strings, Boolean, Array and Object, which I explain with simple examples to understand real life use cases of how these data types are useful in programming. 👩🏻‍💻
Variables is another very important concept in software development in general. Based on simple use cases you will understand what variables are and why you need them.

Some of the scenarios covered:
