- How to create an array containing 1. . . N - Stack Overflow
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:
- How do I declare an array in Python? - Stack Overflow
The array structure has stricter rules than a list or np array, and this can reduce errors and make debugging easier, especially when working with numerical data
- How can I initialize all members of an array to the same value?
How would you use memset to initialize a int array to some value larger than 255? memset only works if the array is byte sized
- javascript - Get the last item in an array - Stack Overflow
Array prototype slice with -1 can be used to create a new Array containing only the last item of the original Array, you can then use Destructuring Assignment to create a variable using the first item of that new Array
- How can you sort an array without mutating the original array?

Array filter() with a nested call to find() will return all elements in the first array that are members of the second array Check the length of the returned array to determine if any of the second array were in the first array
- What are the advantages of using std::array over C-style arrays?
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
