Identify Reusable Components

Prior to starting development on a new project, make sure to familiarize yourself with the UI/UX of the whole project. Thoroughly analyze the design files provided by the UX designers, take note of the trends across different pages, and start mapping similar pieces of UI into reusable components (containers, sections, etc).

Component identification can be difficult at first, but it will pay off rather soon as it results in consistent UI and minimal repetition of code (think how much easier bug fixes or enhancements will become if your only need to change your code in one place).
