Feynman Understanding:
If a webpage is a house, HTML is the framework, CSS is the decoration, then JavaScript is the electricity that makes things work. It's like having a magic button - when you click it, something happens. Like alert('hello') shows a popup, + name) can greet people by name. JavaScript makes webpages interactive.
Example Questions:
- •What is JavaScript?
- •How do you create variables?
Feynman Understanding:
Think of building a house. HTML is those wooden frame, CSS is decoration, and JavaScript is electricity and plumbing. HTML tells the browser 'this is a title, this is a paragraph, this is an image' by using different tags. Like <h1> means big title, <p> means paragraph, <img> means image.
Example Questions:
- •What is HTML?
- •What are HTML tags?
Feynman Understanding:
If HTML is a house frame, then CSS is the decorator. It decides what color the walls are, where the furniture goes, how big the rooms are. CSS tells the browser 'make this text red', 'make this box round', 'put this element on the left side'. It's like styling with { color: red; } commands.
Example Questions:
- •What is CSS?
- •How do you change text color?
Feynman Understanding:
Data structures are like different ways to organize your stuff. Arrays are like a row of lockers numbered 1,2,3. Linked Lists are like a treasure hunt where each clue points to the next. Stacks are like a pile of plates - last one in, first one out. Trees are like family trees with parents and children.
Example Questions:
- •What is an array?
- •How does a linked list work?
Feynman Understanding:
Think of React Hooks like having a toolbox for your components. useState is like having a sticky note to remember things, useEffect is like setting a reminder to do something when certain things change. Instead of complex class components, hooks let you add superpowers to simple functions.
Example Questions:
- •What are React Hooks?
- •How does useState work?
Feynman Understanding:
Imagine you're playing pool. When you hit the cue ball, it moves and hits other balls. That's mechanics - how things move and why. Force is like pushing, acceleration is how fast something speeds up, and momentum is like how hard it is to stop a moving truck vs a bicycle.
Example Questions:
- •What is force?
- •What is Newton's first law?
