Concurrency Model ↔ (mechanism) to achieve Concurrency for JS Engine via Event Loop, Callback Queue & Callback Function

JS needs Concurrency Model to handle async function since most JS Engine run on single Execution Thread

Async​

of process to occur in parallel, independently

Sync​

Runtime behaviour to execute Code sequentially line-by-line in exact order, tends to be Blocking

  2. **Event Loop** ↔ (mechanism) to orchestrate Non-Blocking Concurrency Model by manageCallback Functions between Callback Queue& Call Stack, to await execute
