2.2 Declarations

📌 A declaration names a program entity and specifies some or all of its properties. There are four major kinds of declarations: var, const, type, and func.

2.7 Scope

📌 The scope of a declaration is the part of the source code where a use of the declared name refers to that declaration.

📌 Don’t confuse scope with lifetime. The scope of a declaration is a region of the program text; it is a compile-time property. The lifetime of a variable is the range of time during execution when the variable can be referred to by other parts of the program; it is a run-time property.
