This is my complete path and roadmap with the code i have practised to master javascript. This documentation of my journey will be the proof of my work and improvement

High level progression -variables and datatypes -Different kinds of operators and its precedence -Expression , statements -str concatination , multiline string, comments and template literals -conditional if - else if - else statements , switch statements and terenary operator -type conversion and type cohersion in - str , number and boolean -Loops in js , how to do nested looping - for,while,do while -Arrays and its depths -Functions and its depths -Objects and its depths -Classes and its depths -OOPS concepts in JS -Callbacks -Asyncronous Javascript concept -Promises -Async/await
