I wanted to start a broader mistakes and lessons thread around JavaScript.

A useful angle is automation, but it also connects with privacy considerations. Different tools and workflows can produce very different results even when the goal is similar.

It would be interesting to compare practical examples, experiments, setups, or lessons that show where JavaScript is genuinely useful and where it still needs improvement.
