JavaScript Interview Guide — Happy Rawat (PDF-ready)

The "Free Upd" Illusion

You want the "free upd" (update). You want the latest version. But here is the secret the grind culture won't tell you:

JavaScript updates every year (ES2023, ES2024). The PDF updates every never.

The moment you download a static PDF, you are studying history. You aren't learning the language; you are memorizing a snapshot of somebody else's notes.

5. Coding Problems (with hints & short solutions)

  1. Reverse a string — use split/reverse/join or two-pointer swap.
  2. Check palindrome — compare with reversed or two-pointer.
  3. Flatten nested arrays — recursion or stack.
  4. Unique values in array — Set or object map.
  5. Implement Promise.all — collect results, reject on first error.
  6. LRU Cache — use Map for O(1) get/put with eviction.
  7. Debounce & Throttle — implementations:

Debounce (ES6):

function debounce(fn, wait=300)
  let t;
  return (...args)=>
    clearTimeout(t);
    t = setTimeout(()=>fn.apply(this, args), wait);
  ;

Throttle:

function throttle(fn, limit=250)
  let last = 0;
  return (...args)=>
    const now = Date.now();
    if(now - last >= limit)
      last = now;
      fn.apply(this, args);
;
  1. Implement flatMap, map, reduce polyfills — use prototypes and careful thisArg handling.
