Writing Javascript without a build system

They provide examples of the difficulties they've had in building old projects and note that some libraries require build systems to use their latest versions.

The author provides tips for using JavaScript libraries without a build system, including searching for a CDN or hosting their own version of the library. They also mention esbuild as a more reliable build system option.
