Tips for Building Projects That Get You Hired
- 1
Avoid jQuery — write modern vanilla JS with ES6+ features. Interviewers notice immediately.
- 2
Understand async deeply — Promises, async/await, and the event loop come up in almost every JS interview.
- 3
Add a Node.js or Express backend to at least one project — full-stack thinking is expected even for frontend roles.
- 4
Use the Web APIs — Intersection Observer, Canvas, Web Speech, LocalStorage. They show depth beyond just React.
- 5
Host on Netlify or Vercel with a custom domain — presentation is part of the project.
