By the end you'll be able to
- Work with legacy jQuery projects
- Build interactive UI components
- Implement AJAX-based features
- Understand classic frontend patterns
- Extend jQuery with plugins
Is this course for you?
This is right for you if you…
- You're job-hunting and finding 'jQuery experience' on real job ads — it's not dead in the wild, even if it is in the trends
- You inherited a legacy frontend codebase at work and need to extend it without rewriting it
- You're starting from zero in JS and want a forgiving entry point — jQuery's API is small and the feedback loop is fast
Don't take this course if you…
- You're starting a new project in 2026 — use vanilla JS or React. jQuery is a maintenance skill, not a green-field one
- You want to build a SPA — jQuery wasn't designed for that scale. Take the React course (#16) instead
- You expect modern frontend interview questions — most senior roles in 2026 don't ask about jQuery; this course pays off in mid-tier and contract work

Prerequisites
Basic computer skills and willingness to learn. Course materials will guide you step by step.
Basic HTML, CSS and JavaScript knowledge required.
What you'll build
You leave able to read, fix, and extend the jQuery codebases that quietly run massive parts of the legacy web — internal tools, e-commerce admin panels, WordPress plugins, banking interfaces. The roles that pay for this skill aren't glamorous, but they're plentiful, stable, and remote-friendly.

- DOM manipulation
- Event handling
- Animations and effects
- AJAX requests
- jQuery UI basics
- Plugin and module creation

First lesson on us. Decide after meeting your instructor.
Sit in on the first session. If after lesson 1 you decide the instructor isn't the right fit, you don't pay for it — and no awkward conversation. (Trial offer applies to courses with more than 5 lessons; this one qualifies.)
Pricing & what's included
What's included
- 10 live sessions × 2 hours each — taught by the instructor, not a recording playback
- Slide deck for every session — yours to keep and refer back to
- Working code files and any data files used in class — cloned to your machine
- Weekly homework with personal code review from the instructor
- Recording on request — give the teacher a heads-up ("can't make Tuesday, please record it") and the session is recorded for you
Frequently asked questions
How much time per week will this take?
Plan for the live sessions plus roughly 1.5–2 hours of practice per session. Most students who finish on schedule put in 4–6 hours a week total. If you put in less, you still finish — it just takes longer.
What if I miss a class?
Tell the teacher BEFORE the session — "I can't make Tuesday, please record it" — and the teacher records that lesson and sends it to you. Recordings aren't a default catch-up archive; they're produced on request when you give a heads-up. After the lesson you do the homework, bring questions to the next session.
What's included in the price?
Live sessions with the teacher; the slide deck for each session (yours to keep); the working code files and any data files used in class; weekly homework with code review; and recordings of the sessions you give advance notice for. Anything beyond that — a certificate, alumni access, mock interviews — is listed explicitly in "What's included" above the FAQ for the courses where it applies.
What if I sign up and the teacher isn't a fit?
For courses with more than 5 lessons, the first session is effectively a trial — if after lesson 1 you decide the teacher isn't a fit, you don't pay for it. We'd rather you walk away after one lesson than push through 9 weeks of bad chemistry. (Courses with 5 or fewer lessons are short enough that the standard pricing applies — the trial offer doesn't make sense at that length.)
Can I get a refund partway through?
Yes, while more than half the course is still unused — i.e. you've attended fewer than 50% of the lessons. The refund covers the unused portion proportionally. Past the halfway point we don't refund, on the assumption that the value has been delivered.
Can I switch the language of instruction?
The live sessions run in the language listed under "Available Languages" above. Slides and code files are typically available in all four (English, Russian, Ukrainian, Georgian). Many students attend sessions in one language and read materials in another — that's normal.
Will I be ready for a real job after this course?
One course rarely gets anyone hired by itself — for any field. What this course gives you is the foundation a junior hiring manager expects: working code you wrote yourself, the vocabulary to read other people's code, and the practice habits that make you employable. The honest answer to "am I ready?" is on our roadmap (link in the page header) — open the level you want to reach and read the "You're ready when" checklist.
Can I pay in instalments?
Yes for courses with a "Monthly Payment" option in the at-a-glance ribbon — usually two or three equal monthly payments. Courses without that option are paid in one go. If the price is the blocker, write to us — we look at every case.
