sizeof can be used to determine the number of elements in an array, by dividing the size of the entire array by the size of a single element. This should be used with caution; When passing an array to another function, it will "decay" to a pointer type. At this point, sizeof will return the size of the pointer, not the total size of the array.
In an apparent transition from JScript to JavaScript, online, the Microsoft Edge [Legacy] Developer Guide refers to the Mozilla MDN web reference library as its definitive documentation. [11] As of October 2017, Microsoft MSDN pages for scripting in Internet Explorer are being redirected there as well. [12]
The sizeof operator on such a struct gives the size of the structure as if the flexible array member were empty. This may include padding added to accommodate the flexible member; the compiler is also free to re-use such padding as part of the array itself.

In computer programming, an operator is a programming language construct that provides functionality that may not be possible to define as a user-defined function (i.e. sizeof in C) or has syntax different than a function (i.e. infix addition as in a+b).

From Part 1: "In C, size is measured in units of unsigned char, and returned as a value of type size_t, which is some unsigned integer type; the size of a type is the number of unsigned char objects it would take to hold all the bits used to store the object. The built-in sizeof operator yields this size."
