Local Variable in JavaScript #codelearningjourney #webdevelopment

A local variable is like a coffee mug you keep only in your office – it doesn’t exist outside that space. In JavaScript, variables declared with let or const inside a function are local and cannot be accessed from outside. Here, coffeeMugs is a local variable, defined with let inside the coffeeInOffice function. It exists only within that function. If you try to access it from outside, JavaScript will tell you it doesn’t exist (ReferenceError).
