Lexical Environment

• Lexical environment is a place where we write code
• Every time we create an execution context, code inside these contexts are under a lexical environment
• When we do the lexical analysis, it find the work or token location or which context it belongs to
• We can consider lexical environment as a planet for execution context
• Lexical environment determine the access of the methods and objects
• The first lexical environment is the global execution context
