but reassigning a new value to the reference within the method has no effect on the reference in the calling scope, which is exactly the behavior you would expect of a pointer to a struct in C or an object in C++.
Since arrays are passed by default as a pointer to their first element and not copied, changing the value of an element of the array in a function effectively results in changing the value of that element of the array in the function caller, which is why the above code outputs 0 0...

Every now and then the talk is "JS Arrays are objects and hence they are passed by reference". However, simple experiments leave my puzzled: It's the same as with light (depending on the view it behaves as waves or as particles): gaSomething = ["a","b", "c"];Update (gaSom...
Pointers are used in C to achieve pass-by-reference semantics, allowing functions to modify variables passed as arguments, to navigate through arrays efficiently, and to manage dynamic data structures. Basic Pointer Operations Basic operations with pointers include dereferencing, arithmetic operations, ...

Large palindromes on mammalian sex chromosomes are typically found as isolated pairs of palindrome arms (singleton palindromes) or in complex arrays of palindromes. We investigated singleton palindromes, because they are more commonly found across mammalian sex chromosomes and can be genetically manipulated...
Arrays of objects are passed by value (the array) but each object is passed by reference. <?php $obj=new stdClass(); $obj->field='world'; $original=array($obj); function example($hello) { $hello[0]->field='mundo'; // change will be applied in $original $hello[1]=new stdClass...
