# HTML, CSS, JavaScript, and React

<mark style="color:red;">**HTML + CSS + JavaScript + React**</mark> is the standard front end development skill stack for web3 developers.

I recommend you learn it since it opens potential job opportunities and these things are not very difficult to learn. Usually I expect a beginner to grasp this knowledge and build an independent portfolio project within 3 months.
