Build
aka: compileaka: build step
The Quick Version
Turning your source code into the optimised files a browser can run.
How it actually works
A build bundles, transforms and minifies your code, type-checks it, and produces a dist/ or .output/ folder. It is where most deployment failures happen — and where they should happen, before users see them.
Why does it matter?
'Works on my machine' usually means the dev server worked but nobody ever ran a production build.
Example
npm run build
