We'll use that fact later. Array.apply(null, [undefined, undefined, undefined]) is equivalent to Array(undefined, undefined, undefined), which produces a three-element array and assigns undefined to each element. How can you generalize that to N elements? Consider how Array() works, which goes something like this:
I'm analyzing some Python code and I don't know what pop = population[:] means. Is it something like array lists in Java or like a bi-dimensional array?
40 std::array is designed as zero-overhead wrapper for C arrays that gives it the "normal" value like semantics of the other C++ containers. You should not notice any difference in runtime performance while you still get to enjoy the extra features. Using std::array instead of int[] style arrays is a good idea if you have C++11 or boost at hand.
How do I remove a specific value from an array? Something like: array.remove(value); Constraints: I have to use core JavaScript. Frameworks are not allowed.
An array sent as a parameter to a function is treated as a pointer, so sizeof will return the pointer's size, instead of the array's. Thus, inside functions this method does not work. Instead, always pass an additional parameter size_t size indicating the number of elements in the array. Test:
