📌 JavaScript Tip: Understand the concept of 'closures' - functions that remember the scope in which they were created. Closures allow functions to access and use variables from their parent function even after the parent function has finished executing. Example:

function outerFunction() {
  const outerVar = 'I am from the outer function';
  
  function innerFunction() {
    console.log(outerVar); // Accessing outerVar from the outer function
  }
  
  return innerFunction;
}

const myFunction = outerFunction();
myFunction(); // Output: 'I am from the outer function'
