The Math.sign() static method returns 1 or -1, indicating the sign of the number passed as argument. If the input is 0 or -0, it will be returned as-is.

The Symbol.toStringTag static data property represents the well-known symbol @@toStringTag. Object.prototype.toString() looks up this symbol on the this value for the property containing a string that represents the type of the object.

The Error() constructor creates Error objects.

The arguments accessor property of Function instances returns the arguments passed to this function. For strict, arrow, async, and generator functions, accessing the arguments property throws a TypeError.

The [@@hasInstance]() method of Function instances specifies the default procedure for determining if a constructor function recognizes an object as one of the constructor's instances. It is called by the instanceof operator.

The columnNumber data property of an Error instance contains the column number in the line of the file that raised this error.

The lineNumber data property of an Error instance contains the line number in the file that raised this error.

The Symbol.toPrimitive static data property represents the well-known symbol @@toPrimitive. All type coercion algorithms look up this symbol on objects for the method that accepts a preferred type and returns a primitive representation of the object, before falling back to using the object's valueOf() and toString() methods.

The [@@toPrimitive]() method of Date instances returns a primitive value representing this date. It may either be a string or a number, depending on the hint given.

The Math.sin() static method returns the sine of a number in radians.
