What Dylano Zuijderwijk said is correct. Let keyword was introduced in ES6 (6th version of JS) because function scopes was confusing and one of the main bugs of javascript. Because of this it is very uncommon to use var actually

Where is the storage area for let and var type of variable in side system. Does system environment and kernel space is accessible ? It has ability to access system software information through browser and it's plugins. Apologize to put off topic queries.

Var is accessible in the whole code while Let is only accessible inside the block/scope it was defined
