Hoisting from today's js interview call
........this is saying copilot: Hoisting with let and const:
In summary, while all declarations (including let, const, and var) are hoisted, the behavior differs:
- var variables are hoisted with default initialization (value: undefined).
- let and const variables are hoisted without initialization, leading to a temporal dead zone where they cannot be accessed before declaration12.
- ................................This is from MDN docs:
- let declarations can only be accessed after the place of declaration is reached (see temporal dead zone). For this reason, let declarations are commonly regarded as non-hoisted.

- const declarations can only be accessed after the place of declaration is reached (see temporal dead zone). For this reason, const declarations are commonly regarded as non-hoisted.
