What are the phases of execution context?

What are the phases of execution context?

1. Creation Phase:

   • Memory is allocated for variables and functions.
   • Variables are initialized with undefined.
   • Functions are stored as-is.

2. Execution Phase:

   • Code is executed line by line.
   • Variables are assigned actual values.

Example:

function test() {
  console.log(a); // undefined (creation phase)
  var a = 10;
  console.log(a); // 10 (execution phase)
}

test();
