1. What is Svelte?
- A library like React
- Compiler that converts components to efficient JavaScript
- A JavaScript framework
- A CSS framework
Show answer
Answer: Compiler that converts components to efficient JavaScript. Svelte is a compiler, not a framework. It compiles components to highly efficient imperative code at build time. No virtual DOM. Truly reactive. Less code, better performance.
2. What makes Svelte different from React/Vue?
- Different syntax
- Better components
- Compile-time framework, no virtual DOM, truly reactive
- Faster rendering
Show answer
Answer: Compile-time framework, no virtual DOM, truly reactive. Svelte compiles to vanilla JS at build time. No runtime overhead. No virtual DOM diffing. Truly reactive - updates DOM surgically. Smaller bundle sizes. Write less code.
3. How do you declare a reactive variable?
- const count = ref(0);
- state count = 0;
- reactive count = 0;
- let count = 0;
Show answer
Answer: let count = 0;. Just use let: let count = 0. Svelte compiler makes it reactive. Assignments trigger updates: count += 1. No setState, no refs. Simple JavaScript.
