Basic idea about Mark & Sweep Algo: It comprise of 2 phases - 1. Mark phase 2. Sweep phase All objects are marked as 0 initially (at creation) and in mark phase the objects that will be accessible are marked as 1 (reachable) by a DFS graph traversal. During sweep phase, the objects marked with 0 are removed from heap memory. and also all reachable objects are again initialized with 0 (made unreachable) because the algorithm will run again. So, it's basically tracing garbage collector concept. :)

Things learned: 1. JS runtime environment contains all elements required to run JS. 2. It contains JS engine, set of API's, callback queue, microtask queue, event loop. 3. JS engine is a piece of code. 4. Process includes Parsing ---> Compilation -----> Execution. 5. Parsing breaks code into tokens and converts it into AST(Abstract Syntax Tree). 6. Modern JS engine follows JIT compilation, it interprets while it optimises code as much as it can. 7. Execution and Compilation are done together. 8. Execution has Garbage collector and other optimisation such as inlining, copy elusion, inline caching etc. 9. Fell in love with JS. ❤❤

Learning about the architecture of a JavaScript engine like Google's V8 can be fascinating, and it's wonderful to see educational resources like the Namaste JavaScript podcast bringing this knowledge to a wider audience. By improving our understanding of the technology behind programming languages, we can become better developers and create more efficient and effective code.

@@harshneetsingh5267 JS is so vast that mastering it will take a lot of time. If your intention is to be a front-end developer then covering JS topics like fundamentals, higher order functions, Async/await, ES6, API calls are fine to move on to a framework like React, in my opinion.

[@shubhamqweasd]

One small thing/correction to add- MicroTask Queue is a part of the Engine and some engines like Chakra don't even have it, MicroTask queue is V8 engine specific "term". For other engines its called PromiseJobs (ECMA spec), implementation of it is very Engine dependent. That means even in the absence of an EventLoop(platform), you can ask the engine to process your promise callbacks, i.e there is no need of an event loop to execute a promise. Source: Worked with V8 and event loops. Link: v8docs.nodesource.com/node-12.0/db/d08/classv8_1_1_microtask_queue.html
