Here's a comparison between how the same simple user definition would be defined using ArkType and Zod:

ArkType's definition syntax is more concise (definitions are about 50% shorter on average) as well as making it more visually obvious what the inferred TypeScript type will be. The ability to infer TypeScript definitions directly is the same, but ArkType's syntax is again more concise by allowing you to use typeof on a property of arkUser directly instead of using an extra "infer" helper.

In general, we also have taken significant steps to optimize and clarify our type hints when hovering over validators. For example, in the case above, this is what you see when you mouse over "zodUser":

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

import rootReducer from '../my-rootreducer-dir';

function renderWithRedux(ui, { initialState, store = createStore(rootReducer, initialState) } = {}, renderFn = render) {
  const obj = {
    ...renderFn(<Provider store={store}>{ui}</Provider>),
    store,
  };
  obj.rerenderWithRedux = (el, nextState) => {
