I am looking to sever connections within JavaScript references

I am facing an issue with two arrays in my AngularJS project. One array is initially empty, and I assign the content of the other array to this empty one using a statement like 

$scope.module_Allquestions = $scope.module_questions.questions;
.

My concern is about breaking the references between these two arrays. While I know that in ES6 we can use the spread operator for this purpose, I have been informed that it may not be feasible in AngularJS as it does not fully support ES6 yet. Are there any alternative methods available in AngularJS to achieve this without referencing the arrays?

Thank you.

Answer №1

Someone told me that in AngularJS, which is behind ES6, I wouldn't be able to use spread syntax.

Actually, that information is incorrect. Angular is simply a JavaScript library, so you can definitely use spread syntax as long as the JS engine supports it (which most modern browsers do, except for IE 11). If needed, you can always transpile your code to ES5 for compatibility.

There are also other options like 

Array.from(scope.module_questions.questions)
and 
scope.module_questions.questions.slice()
for shallow copies. For more complex data structures, consider using the Immer library.

Answer №2

To tailor your approach to suit your specific content, consider utilizing a copying method like 

$scope.module_Allquestions = JSON.parse(JSON.stringify($scope.module_questions.questions));
