new Promise.all()

[xilibro]

const iconsLoaded = new Promise((resolve, reject) => {
	new Promise.all(
		Object.keys(icons).map(iconName =>
		// IconName--suffix--other-suffix is just the mapping name in iconsMap
		Ionicons.getImageSource(
		iconName.replace(replaceSuffixPattern, ''),
		icons[iconName][0],
		icons[iconName][1]
		))
	).then(sources => {
		Object.keys(icons)
		.forEach((iconName, idx) => (iconsMap[iconName] = sources[idx]));

		// Call resolve (and we are done)
		resolve(true);
	});
});

who can help me understand why following code working:
new Promise.all().then() ... i test this code in jsfiddle tell me an TypeError:
Promise.all is not a constructor

Probably a bit late on this, but
Just use:

Promise.all

instead of

new Promise.all()

all is a static function of Promise.
