String Array. String Array. Array of strings. Can only contain strings. Optimized for memory usage, can't fragment the memory. Note that this type is passed by value and not by reference. Create from a generic array. Append an element at the end of the array (alias of [method push_back]). Append an [StringArray] at the end of this array. Insert a new element at a given position in the array. The position must be valid, or at the end of the array (pos==size()). Reverse the order of the elements in the array (so first element will now be the last). Returns a [String] with each element of the array joined with the delimiter. Append a string element at end of the array. Remove an element from the array by index. Set the size of the array. If the array is grown reserve elements at the end of the array. If the array is shrunk truncate the array to the new size. Change the [String] at the given index. Return the size of the array.
