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

Data Types ✅

I cover JavaScript's 5 data types, which are:
JavaScript Data Types

I explain them with simple examples to understand real life use cases of how these data types are useful in programming. 👩🏻‍💻

Variables ✅

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 in the video:

  • online shop
  • user input
  • social media websites

Online shop prices - WITHOUT variables:
JavaScript without Variables

Online shop prices - WITH variables:
JavaScript with Variables

User Input WITH variables
JavaScript User Input

When working with user input, you must use variables. Because you don’t know what the values will be 🤷🏻‍♀️
