Newly available across browsers

Float16Array: Float16Array is a typed array of 16-bit floating point numbers.
Atomics.pause(): The Atomics.pause() static method gives a hint to the CPU that the code calling the method is in a short-duration wait for shared memory, known as spinning or a spinlock.
ClipboardItem.supports(): The ClipboardItem.supports() static method checks if the browser supports writing data types such as "image/svg+xml" or other custom formats to the system clipboard.
Screen wake lock: The navigator.wakeLock.request("screen") API prevents the device's screen from dimming or being turned off.
contenteditable="plaintext-only": The contenteditable="plaintext-only" global HTML attribute allows the user to edit the content of an element, but prevents rich-text formatting.

Inline-size containment: The contain: inline-size CSS declaration prevents the element's inline dimension from being set by the element's contents. This permits the browser to avoid slower layout calculations.
Motion path: The offset CSS property animates an element along a defined motion path.
Array findLast() and findLastIndex(): The findLast() and findLastIndex() methods of arrays and typed arrays search an array in reverse order for the first item that satisfies a test function.
Style containment: The contain: style CSS declaration permits the browser to avoid slower layout calculations by preventing modification to counter (counter-increment and counter-set) and quotation styles (content property quote values) beyond the element's descendants.
appearance: The appearance CSS property controls the appearance of form controls. Using appearance: none disables any default native appearance and allows the elements to be styled with CSS.
