StylePropertyMapReadOnly: entries() method
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The StylePropertyMapReadOnly.entries() method returns an
array of a given object's own enumerable property [key, value] pairs, in
the same order as that provided by a for...in loop
(the difference being that a for-in loop enumerates properties in the prototype chain as
well).
Syntax
js
entries()
Parameters
None.
Return value
An array of the given StylePropertyMapReadOnly object's own enumerable
property [key, value] pairs.
Examples
Here shows an example of using StylePropertyMapReadOnly.entries() method
on an elements computed styles.
js
// grab a DOM element
const buttonEl = document.querySelector("button");
// we can retrieve all computed styles with `computedStyleMap`
const allComputedStyles = buttonEl.computedStyleMap();
// entries returns an iterable of the items
const iterableStyles = allComputedStyles.entries();
// returns a two item array with align-content as the first item and CSSStyleValue as the second
console.log(iterableStyles.next().value);
