MindCraft Frontend Web Dev - JS Essential Lecture 2
Course by: MindCraft
In this lecture, we delve deep into understanding how JavaScript operates behind the scenes within the JS Engine. We cover the crucial concept of Execution Context, exploring its creation and the two key phases: Memory Allocation Phase and Code Execution Phase.
We'll address fundamental questions such as whether JavaScript is single-threaded or multi-threaded, and whether it operates synchronously or asynchronously. These concepts often cause confusion among JavaScript developers, and this video aims to clarify them comprehensively.
