Number() constructor

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

Return value: When Number() is called as a function (without new), it returns value coerced to a number primitive. Specially, BigInts values are converted to numbers instead of throwing. If value is absent, it becomes 0.

Return value: When Number() is called as a constructor (with new), it uses the coercion process above and returns a wrapping Number object, which is not a primitive.

Return value: Warning: You should rarely find yourself using Number as a constructor.

Parameters: value The numeric value of the object being created.

Syntax example: new Number(value)
