Add a logpoint in devtools to log runtime values without adding console.log() or debugger in code.
Discovery of the day: devtools logpoints. Instead of adding console.log directly in the code, you can add a logpoint in devtools (at least in Chrome). The brilliant @jec.fish has a video about this: youtu.be/JyHjoaUhAus. No more forgotten log lines! ππ»

If you're using Speculation Rules there's a small bug in Chrome 133 (just rolling out now) where DevTools + Local Overrides causes prerenders to crash π’
This only happens with DevTools open and when Local Overrides are enabled so shouldn't affect most of your usersβbut annoying for us developers!

Good news for those of you who prefer to keep classic #ChromeDevTools color scheme.
We added a setting to let you customize that via Settings > Preferences > Match Chrome color scheme.

Object.assign() - JavaScript | MDN
The Object.assign() static method copies all enumerable own properties from one or more source objects to a target object. It returns the modified target object.
TIL Object.assign makes DOM creation more compact:
document.body.appendChild(
Object.assign(
document.createElement('div'),
{ className: 'foo', textContent: 'Hi' }
)
);
