Quality of practice, not problem count

Practice recognizing the pattern, not remembering yesterday’s answer.

Choose one exercise, attempt it under time, use a hint only when needed, then return after a scheduled gap.

typescript-interview-sprint: terminal
$ ./grind next

two-sum: Two Sum (core · 20 min)

$ ./grind attempt two-sum

Attempt started. Open solution.ts in your editor.

$ ./grind test two-sum

✗ returns indices whose values add to the target

$ ./grind hint two-sum 1

What value would complete the current number to reach the target?

$ ./grind solve two-sum --independent

✓ Solved independently. Review scheduled tomorrow

solution.ts
export function twoSum(
  numbers: number[],
  target: number,
): [number, number] {
  // Your implementation here.
  throw new Error('TODO');
}

Two Sum

Return the indices of two different values whose sum equals the target.

Recognition cue

You need a pair and can derive the missing value while scanning once.

Original briefs and hintsUse three staged hints only when needed.

A route you can finish

Open the folder. Know what to practice next.

01

No daily selection problem

Follow a seven-day or 14-day route instead of deciding among hundreds of questions.

02

Feedback in your terminal

Run typed starter code against tests without learning another browser workspace.

03

Repeat after a real gap

Reviews return after 1, 3, 7, 14, and 30 days to test retrieval.

04

Your work stays yours

Your solutions, notes, and progress stay in the downloaded folder.

Use this when

Your coding round is approaching and you want a small, structured refresher.

Do not buy this for

Learning TypeScript from zero or preparing the complete frontend interview loop.

Reasonable objections

Know exactly what this replaces, and what it does not.

Why not use a free question bank?

Use one when you want breadth. This pack is for a short deadline: a fixed route, local TypeScript files, tests, hints, and scheduled review without choosing the next problem.

Will 15 exercises make me interview-ready?

No product can guarantee that. These exercises refresh eight common pattern families. They do not cover every question or every interview format.

Are complete solutions included?

No. You receive starters, tests, reflection prompts, and three staged hints. The goal is to retrieve an approach, not copy one.

What do I need?

You should already know basic TypeScript. You also need macOS, Linux, or Windows, Bun 1.2 or later, and any text editor.

Does this cover frontend interviews?

Only the coding-pattern portion. It does not cover React, user-interface coding, browser APIs, system design, behavioral rounds, or company-specific questions.

What support is included?

Support covers broken downloads, installation defects, incorrect tests, and reproducible command errors. It does not include coaching or solution review.

Check the fit before you pay

Try the actual workflow on one complete exercise.

No email wall. Inspect the brief, starter, tests, hints, CLI, and reflection prompt.
