Thanks, that’s helpful. Could you tell me about how you’ve worked with product managers, designers, and other engineers on a project? Thanks, that gives a clear picture. Have you had situations where you needed to explain front-end tradeoffs to product leadership, for example around scope, UX, performance, or technical constraints? Are you available to work from the office in Poznań 1 day per quarter if you’re based outside Poznań?

console.log("foo"); setTimeout(() => { console.log("bar"); }, 0); queueMicrotask(() => { console.log("baz"); Promise.resolve() .then(() => console.log("ban")); }); new Promise((resolve) => { console.log("bla"); resolve("baf"); }).then(console.log); console.log("bak"); //// foo bla bak baz baf ban bar

What is a Promise and how does it work?

The function simulates the rotation of a drum with a gradual stop - use onRoll for the rotation animation (changing the current value on the drum) - and onStop to notify when the drum has finished spinning example runSpinner( () => setValue(v => ++v % 10), () => console.log('finished') )
