What is the difference between lexical scoping and dynamic scoping?

Answer

Lexical scoping refers to when the location of a function's definition determines which variables you have access to. On the other hand, dynamic scoping uses the location of the function's invocation to determine which variables are available.

Good to hear

  • Lexical scoping is also known as static scoping.

  • Lexical scoping in JavaScript allows for the concept of closures.

  • Most languages use lexical scoping because it tends to promote source code that is more easily understood.
