3 DaysFrequently Asked Questions
Do I need HTML and CSS first?
Yes, the basics. Our 15-day HTML and 20-day CSS courses are the ideal start – this course adds behaviour to the same Sharma Sweets website.
Can I run the code without installing anything?
Yes. Browser examples run right on the page, and every Node.js example shows its real output. For your own practice you only need a browser and VS Code; Node.js is optional until Day 21.
Is this enough for a front-end job?
HTML + CSS + this course take you to junior front-end level: you can build interactive pages, call APIs and explain your code in interviews. Next learn React and put the three projects on GitHub.
How much time does it take per day?
About 1.5 to 2 hours per day including practice; the project days take 3–4 hours. It is 100% self-paced.
Where are the files?
Log in and use “Download All Examples + Projects”: every browser example as an .html file, every Node.js example as a .js file, practice solutions and all three complete projects.
