I began programming in various languagesâASP, Perl, PHP, ActionScript, Visual Basic and Javaâbefore discovering that JavaScript was still a relatively slow browser language when I started; I therefore used Perl/PHP on the server while writing client-side code in JavaScript. After experimenting with Rhino on my phone for an interval timer, Node.jsâs release prompted me to fully adopt JavaScript: its runtimes (Node.js, Bun, Deno) let me write both frontâend and backâend code, while Electron or nw.js provide strippedâdown browsers for crossâplatform desktop apps. Mastering JavaScript opens doors to browser extensions, custom HTTP servers, commandâline utilities that can be compiled into executables, mobile apps via React Native, NativeScript or Cordova, and even AIâassisted developmentâtodayâs AI tools can generate working code snippets (e.g., a commandâline parser) on demand, making JavaScript an incredibly versatile and powerful openâsource stack.
