The getUint32() method of DataView instances reads 4 bytes starting at the specified byte offset of this DataView and interprets them as a 32-bit unsigned integer. There is no alignment constraint; multi-byte values may be fetched from any offset within bounds.

The getFloat32() method of DataView instances reads 4 bytes starting at the specified byte offset of this DataView and interprets them as a 32-bit floating point number. There is no alignment constraint; multi-byte values may be fetched from any offset within bounds.

The setInt16() method of DataView instances takes a number and stores it as a 16-bit signed integer in the 2 bytes starting at the specified byte offset of this DataView. There is no alignment constraint; multi-byte values may be stored at any offset within bounds.

The reduce() method of TypedArray instances executes a user-supplied "reducer" callback function on each element of the typed array, in order, passing in the return value from the calculation on the preceding element. The final result of running the reducer across all elements of the typed array is a single value. This method has the same algorithm as Array.prototype.reduce().

The fileName data property of an Error instance contains the path to the file that raised this error.

The getTimezoneOffset() method of Date instances returns the difference, in minutes, between this date as evaluated in the UTC time zone, and the same date as evaluated in the local time zone.

The forEach() method of Set instances executes a provided function once for each value in this set, in insertion order.

The register() method of FinalizationRegistry instances registers an value with this FinalizationRegistry so that if the value is garbage-collected, the registry's callback may get called.

The unregister() method of FinalizationRegistry instances unregisters a target value from this FinalizationRegistry.

The getUTCSeconds() method of Date instances returns the seconds in the specified date according to universal time.
