Common Viva Questions & Answers
Prepare for your college viva with these commonly asked questions. Each question includes a detailed answer to help you understand the concepts better.
1. What is HTML and its role in web development?
HTML (HyperText Markup Language) is the standard markup language for creating web pages. It provides the structure and content of a webpage through elements like headings, paragraphs, images, and links. HTML works with CSS (styling) and JavaScript (behavior) to create complete web applications.
2. Difference between class and id selectors in CSS?
Class selector (.) can be used on multiple elements and an element can have multiple classes. ID selector (#) should be unique per page and an element can have only one ID. IDs have higher specificity than classes in CSS.
3. What is JavaScript used for in web pages?
JavaScript adds interactivity to web pages. It can: manipulate DOM elements, handle user events, validate forms, create animations, make API calls, store data locally, and build complex web applications. It's the programming language of the web that runs in browsers.
4. Explain localStorage and sessionStorage?
Both are web storage APIs. localStorage persists data even after browser closes (until explicitly cleared). sessionStorage stores data only for the session (cleared when tab/browser closes). Both store data as key-value pairs and are limited to ~5-10MB per origin.
5. What is DOM manipulation in JavaScript?
DOM (Document Object Model) manipulation refers to using JavaScript to dynamically access, modify, add, or delete HTML elements and their attributes/styles/content. Common methods include getElementById, querySelector, createElement, appendChild, and addEventListener.
6. Difference between let, const, and var?
var is function-scoped and can be redeclared. let is block-scoped and cannot be redeclared in the same scope. const is block-scoped, cannot be redeclared, and cannot be reassigned after initialization. Use const by default, let when reassignment is needed, and avoid var.
7. What are JavaScript promises?
Promises represent the eventual completion (or failure) of an asynchronous operation. They have three states: pending, fulfilled, or rejected. Promises help avoid callback hell and make async code more readable using .then() and .catch() methods or async/await syntax.
8. Explain CSS Flexbox and Grid?
Flexbox is one-dimensional layout for arranging items in rows OR columns. Great for component-level layouts. CSS Grid is two-dimensional for rows AND columns simultaneously. Better for page-level layouts. Both are responsive and work well together.
9. What is responsive web design?
Responsive web design ensures websites work well on all devices (desktop, tablet, mobile) by using flexible layouts, fluid grids, flexible images, and CSS media queries. The viewport meta tag is essential for responsive design on mobile devices.
10. How does event bubbling work in JavaScript?
Event bubbling is when an event starts at the target element and bubbles up to its ancestors in the DOM tree. The opposite is event capturing (top-down). You can control this with addEventListener's third parameter. event.stopPropagation() stops the bubbling.
