The Symbol() function returns primitive values of type Symbol.

The String() constructor creates String objects. When called as a function, it returns primitive values of type String.

The RegExp.lastMatch static accessor property returns the last matched substring. RegExp["$&"] is an alias for this property.

The fontcolor() method of String values creates a string that embeds this string in a <font> element (<font color="...">str</font>), which causes this string to be displayed in the specified font color.

The trimStart() method of String values removes whitespace from the beginning of this string and returns a new string, without modifying the original string. trimLeft() is an alias of this method.

The RegExp[@@species] static accessor property returns the constructor used to construct copied regular expressions in certain RegExp methods.

The Int32Array typed array represents an array of 32-bit signed integers 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 some() method of TypedArray instances tests whether at least one element in the typed array passes the test implemented by the provided function. It returns true if, in the typed array, it finds an element for which the provided function returns true; otherwise it returns false. It doesn't modify the typed array. This method has the same algorithm as Array.prototype.some().

The reverse() method of TypedArray instances reverses a typed array in place and returns the reference to the same typed array, the first typed array element now becoming the last, and the last typed array element becoming the first. In other words, elements order in the typed array will be turned towards the direction opposite to that previously stated. This method has the same algorithm as Array.prototype.reverse().

The buffer accessor property of TypedArray instances returns the ArrayBuffer or SharedArrayBuffer referenced by this typed array at construction time.
