Work on an open-source project or at a company with someone who knows the answer to this question and has been doing it for many years.<p>A frustrating fact about coding is that you don&#x27;t know what you don&#x27;t know. You feel like an expert, and then someone else shoots you down by introducing you to a new security risk you&#x27;ve never heard of or a technique that&#x27;s better than the one you&#x27;ve been using.<p>This risk is a lot lower when you have an experienced team around you. Whatever you <i>might</i> be missing, someone else has a chance of catching it.<p>It&#x27;s also much easier to write production-level code when you use a language with robust typing and mature, widely-used, well-tested libraries.
