The Intl.Collator object is a constructor for collators, objects that enable language sensitive string comparison.

Collator Internationalization JavaScript

The Intl.Collator.supportedLocalesOf() method returns an array containing those of the provided locales that are supported in collation without having to fall back to the runtime's default locale.

The Date.parse() method parses a string representation of a date, and returns the number of milliseconds since January 1, 1970, 00:00:00 UTC or NaN if the string is unrecognised or, in some cases, contains illegal date values (e.g. 2015-02-31).

The Float32Array typed array represents an array of 32-bit floating point numbers (corresponding to the C float data type) in the platform byte order. If control over byte order is needed, use DataView instead. The contents are initialized to 0. Once established, you can reference elements in the array using the object's methods, or using standard array index syntax (that is, using bracket notation).

The SIMD.Float32x4 data type is a 128-bit vector divided into 4 lanes storing single precision floating point values.
