An example of an AI chatbot conversation about JavaScript execution context.
What is the execution context in JavaScript?
The execution context is the environment in which JavaScript code is evaluated and executed. It includes the scope, variables, and the value of 'this'.
Can you explain the different types of execution contexts?
Sure! There are three main types: Global Execution Context, Function Execution Context, and Eval Execution Context.
How does the execution context affect variable scope?
The execution context determines the scope chain, which affects how variables are accessed and resolved during execution.
What happens when a function is invoked?
When a function is invoked, a new execution context is created, which includes its own scope and 'this' value.
