Maybe AI is THE "hot" topic, but interviews are as old as ever. As i am studying for that said interviews, I compiled a list of 10 JS topics I think that are very crucial to prove the understanding of.
1. Execution Context & Hoisting
Before JS runs your code, it creates an execution context. A new context is created when a program starts or when a new function is executed. During this phase it allocates memory for variables and functions. var variables are hoisted and initialised as undefined, while let and const are hoisted but remain in the Temporal Dead Zone until their declaration.
Example
console.log(a); // undefined
