The Math.clz32() static method returns the number of leading zero bits in the 32-bit binary representation of a number.

The Math.sinh() static method returns the hyperbolic sine of a number. That is,

The toLocaleString() method of Array instances returns a string representing the elements of the array. The elements are converted to strings using their toLocaleString methods and these strings are separated by a locale-specific string (such as a comma ",").

The subarray() method of TypedArray instances returns a new typed array on the same ArrayBuffer store and with the same element types as for this typed array. The begin offset is inclusive and the end offset is exclusive.

The TypedArray.BYTES_PER_ELEMENT static data property represents the size in bytes of each element in a typed array.

The slice() method of TypedArray instances returns a copy of a portion of a typed array into a new typed array object selected from start to end (end not included) where start and end represent the index of items in that typed array. The original typed array will not be modified. This method has the same algorithm as Array.prototype.slice().

The padStart() method of String values pads this string with another string (multiple times, if needed) until the resulting string reaches the given length. The padding is applied from the start of this string.

The find() method of TypedArray instances returns the first element in the provided typed array that satisfies the provided testing function. If no values satisfy the testing function, undefined is returned. This method has the same algorithm as Array.prototype.find().

The copyWithin() method of TypedArray instances shallow copies part of this typed array to another location in the same typed array and returns this typed array without modifying its length. This method has the same algorithm as Array.prototype.copyWithin().

The TypedArray[@@species] static accessor property returns the constructor used to construct return values from typed array methods.
