Understanding JavaScript's Variable Declarations: var, let, and const

Dive into the core differences between var, let, and const in JavaScript! This video covers var's function-scoping and its ability to be redeclared and updated, along with its hoisting behavior. We also explore let, which is block-scoped and can't be redeclared in the same scope but can be updated. Finally, we examine const, its block-scoping, mandatory initialization upon declaration, and its immutability. We also touch on how const works with both primitive and complex data types.
