JavaScript’s variables: scopes, environments, closures

JavaScript’s variables are flexible and powerful. This talk will explore the following concepts to give you a deeper understanding of how they work:

  • Scopes determine where variables are accessible. JavaScript’s variables are lexically scoped and function-scoped.
  • Environments are a data structure for storing variables.
  • Closures combine functions and environments to support nested lexical scopes.
