isDouble doesn’t actually check for doubles

[mathiasbynens]

isDouble just checks for numbers:

elements-kinds/index.js

Lines 14 to 23 in 2d96ef5

	/**
	* Handles +-Infinity, Doubles, NaN, -0
	*/
	function isDouble(arr) {
	return arr.every(e => typeof e === "number");
	//return arr.some(
	// e =>
	// Number.isNaN(e) || (Number(e) === e && e % 1 !== 0) || Object.is(e, -0)
	// );
	}

This appears to work fine because of the ordering used here, where isDouble is only used if it’s not an array of Smis:

elements-kinds/index.js

Lines 46 to 50 in 2d96ef5

	if (isSMI(inputArray)) {
	kind = ELEMENTS_KINDS.HOLEY_SMI_ELEMENTS;
	} else if (isDouble(inputArray)) {
	kind = ELEMENTS_KINDS.HOLEY_DOUBLE_ELEMENTS;
	} else {

Suggested fix: either rename isDouble to isNumber, or actually check for double values :)
