Seven Coding Habits That Make Performance Optimization Unnecessary Later

A software developer argues that web performance problems persist because teams treat optimization as a separate phase rather than a daily practice. The article identifies seven habits — such as checking network payload before adding dependencies and using native browser APIs like the HTML dialog element — that eliminate the need for reactive performance fixes. Developers are encouraged to open browser DevTools and simulate slow connections to understand real-world load experiences before shipping features. The piece contends that catching a heavy dependency early is faster than removing it after other parts of the codebase rely on it. Techniques like dynamic imports for non-critical scripts are highlighted as low-effort practices that become automatic over time.
