What is the difference between var, let, and const in JavaScript?
var is function scoped and let and const are block scoped.
Good start! You correctly identified the scoping difference. To strengthen your answer for a junior role, add these points: var allows redeclaration and hoisting behavior (initialized as undefined), let prevents redeclaration in the same scope, and const also requires initialization and prevents reassignment (though objects/arrays can still be mutated). Mention that const and let are preferred in modern JavaScript. This shows you understand not just what, but why and when to use each.
How do you center a div both horizontally and vertically using CSS?
I would use margin: auto on the div.
margin: auto only centers horizontally, not vertically. For a junior frontend role, you should know modern solutions: Flexbox (display: flex; justify-content: center; align-items: center on the parent), CSS Grid (place-items: center), or absolute positioning with transform (position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%)). Explain which method you'd prefer and why—this shows you understand trade-offs and current best practices.
