Learn JSON, or JavaScript Object Notation, which is a very lightweight data interchange format, which is easy to read and write for humans, and easy for machines to generate and parse. JSON is language-independent and can be used with a variety of programming languages, like C, C++, Javascript, Python, Java, etc.

So, learning JSON can enable you to store and exchange data, in a well-organized manner, and a quite standard format, which is easy for both humans and machines.

In this course, we move from scratch, understanding the syntax of JSON, and moving to other things.

At the end of the course, you should have a good understanding of JSON and should be comfortable interpreting the JSON files and creating them. You can then further explore and use JSON as a data format, as and when required in your programs.
