  • Q4. What is closures in js
  • Ans. 

    Closures are functions that have access to variables in their outer scope, even after the outer function has returned.

    • Closures are created when a function is defined inside another function.

    • The inner function has access to the outer function's variables and parameters.

    • Closures can be used to create private variables and methods.

    • Closures can also be used to create functions with pre-set arguments.
