Block Scope in JS

If a variable is declared using “let”, it will only accessible in the { } block in which it was defined. This is called block scope.

Things change if a variable is defined using “var”.
It is the function that limits what is defined with “var”.
This is called a function scope.

Therefore, in the example, we were able to access the one defined by “var” from outside the { } block.
