Job Ready

Recruiters skim a resume in seven seconds and an applicant-tracking system reads it in zero. Both are looking for the same thing: evidence, in the words the posting uses. "Proficient in JavaScript" is not evidence. "Built a React + Express app with 40 Jest tests, deployed on Docker" is.

• Skills: group them — Languages · Front-end · Back-end · Data · Tooling — and list only what you can be interviewed on. Every module in this handbook is a line you can defend.
• Every bullet: action verb, what you built, the tools in parentheses, and a number (users, requests/s, ms saved, % faster, tests).
• Mirror the posting: if it says "TypeScript" say TypeScript, not "typed JavaScript". The ATS matches strings.
• Projects section above Education if you have under three years of experience. Link the repo AND the deployed URL — a front-end project you can click is worth ten you cannot.
• One page. Plain formatting — no columns, tables or icons; ATS parsers mangle them.

Then check it, do not guess: paste the resume and a real posting into the ATS resume checker. It scores keyword coverage against the job, flags the formatting that breaks parsers, and shows which lines a recruiter's eye lands on.

One good project beats ten tutorials. "Good" means: it solves a real (if small) problem, it runs from the README, it is deployed at a URL, it has tests, and it uses the tools from Module 14 the way a job would. These three cover the ground most JavaScript postings ask about, and each is a weekend.

1. 1
   A full-stack app with auth

   Express (or Next.js route handlers) + PostgreSQL + a React front-end: sign up, log in, create and share something — bookmarks, recipes, a reading list. Deployed (Vercel + Neon/Supabase, or Fly/Railway with Docker). Shows: Modules 06, 08, 10, 14 — async, classes, the DOM, Express, pg, Docker.

2. 2
   A data-driven dashboard from a public API

   Fetch from a real API (weather, transit, GitHub, a sports feed), cache it, chart it, make it filterable and fast. Handle the errors and the loading states properly. Shows: fetch and Promise.all, debouncing, immutable state, performance thinking — the mid-level interview questions in code.

3. 3
   A command-line tool or library on npm

   Something you actually use: rename files, summarise a CSV, lint your markdown. Published to npm with TypeScript types, tests, a CI badge and semantic versioning. Shows: modules, packaging, tooling, and that you write JavaScript when nobody asked — the strongest signal there is.

JavaScript has the largest job market of any language, split into three shapes: front-end (React/Next.js, TypeScript, CSS, performance, accessibility), back-end (Node, Express/Fastify/NestJS, databases, queues, Docker), and full-stack (both, usually Next.js). Read the posting's tools list as the interview syllabus — every tool named will come up — and map it to modules.

• Read the verbs: "maintain", "support" → existing codebase, debugging (Module 11 matters). "Design", "build", "own" → greenfield, architecture questions (Module 15 senior tier).
• "Junior" with five years of requirements is a wish list. Apply if you match half; the handbook covers the other half.
• Salary bands correlate with TypeScript, testing and cloud more than with any framework. Those three lines on your resume move the needle.
• Remote JavaScript roles are the most competitive listings on the internet. Apply through a referral or a direct message where you can; the portfolio URL is what gets the reply.

The job board lists JavaScript, TypeScript, React and Node roles with the tools each one names, so you can match a posting to this table before you apply. Set up an alert for the stack you are targeting.

The exam is 25 questions drawn from a bank across Modules 01–13, 35 minutes, 70% to pass. It is not a formality: the questions are the ones interviewers ask, phrased the way they ask them, and the distractors are the misconceptions the modules warn about. Pass it and you get a SolutionGigs JavaScript Programming certificate with your name, score, date and a verifiable ID.

1. 1
   Check the ticks

   The landing page shows every lesson you have completed. Anything unticked in Modules 01–13 is a question you might miss — read it before you sit.

2. 2
   Sit the exam

   Sign in with Google so the certificate can carry your name. You can retake it; the paper is drawn fresh each time.

3. 3
   Put the certificate where it counts

   LinkedIn → Licenses & certifications, with the ID. Resume → Certifications, one line. GitHub profile README → a badge line. Recruiters search LinkedIn for "JavaScript certificate"; the ID lets them verify it.

4. 4
   Then the funnel

   ATS checker with a real posting → fix the gaps → job board → apply with the portfolio URL in the first line.
