Hello everyone,
I am currently working as a Full Stack Developer with focus on Angular, JS, Java and .Net Core, yet sometimes I find myself skeptical in the fundamentals of development. Hence, I have been meaning to improve my skillset starting from the basics 
Thanks to my dear friend and tech enthusiast @SourabhBagrecha for inviting me to this community and motivating me to take this #100daysofcode challenge.
I am looking forward to share my daily updates and progress over the time.
Day 1: Implemented pagination with filter in Angular.
Also went back to the basics !
Revised and did hands on at JS Fundamentals :- Keywords, Destructuring arrays/objects, Rest & Spread operators.
Day 2: Continued the course on JS , topics covered were type conversions, controlling loops, Operators, Function and Block scopes, IIFE’s and Closures.
Day 3: Continuing with JS Fundamentals - this, call, apply and bind methods, Arrow functions, Constructor functions, Prototypes, JSON, Array Methods.
Day 4: Learnt about JS classes, methods, constructors and inheritance. Uses of Module, window object, timers, BOM, DOM and modifying elements of it. Lastly, Error Handling and user defined errors and Promises.
Day 5 : Learnt few things in Angular :- Creating validation for input field using dynamic list, setting conditions for cascading dropdown. Keyup, keydown events with keycode.
Learnt about Callback functions and its limitations, use of Promises. Dug deeper into how JS executes & Execution Context. Concept of Hoisting in JS and also explored some of the developer tools.
Concepts on how JS functions work, their scope, global context and its associated window object and this keyword. Learnt about lexical environment and the working of scope chain, undefined v/s not defined.
Gone through concepts of let, const and temporal dead zone. Also their scope, block scope, shadowing and illegal shadowing in JS.
Went deeper into understanding Closures.
Also learnt setTimeout + closures, but would need more clarity on this.
Finally got closure on Closures with setTimeout functions, and that would be enough for the weekend.
Learnt some of the cool jargons of JS, difference in function statement and function expression, anonymous functions, named function expression and first class functions.
How Event Listeners and callback functions work, blocking of the main thread, closure along with event listener, garbage collection & event listeners.
Learnt about Event Loops, calling of Web APIs, CallBack Queue, MicroTask Queue and how JS works asynchronously in web browsers. setTimeout functions working along with fetch and event listeners.
Theory of JS Engine Architecture, JavaScript Runtime Environment, JIT compilation, Syntax Parsers, Garbage Collector, and how things work behind the scenes in Google’s V8 JS Engine and its architecture.
earnt about High Order Functions in JS and its functional programming, polyfill using map.
Also about Concurrency model in JS using example of setTimeout and setTimeout with 0 delay.
Use cases of Higher Order Functions like Map, Reduce & Filter, with chaining.
Started a much talked about course on Udemy for Web development, begin with introduction to Web, Internet, Request/Response cycle and very basics of HTML.
Continued with HTML basics on block and inline elements, HTML entities, tables and some of the shortcut tricks.
Completed the last section of HTML, it included Forms, different input types and validation.
Did hands on by creating Google search Form and Marathon registration form.
