Struggling with understanding JavaScript syntax. Can someone explain to me why this line of code works:
console.log($rootScope.wg.variable1);
But the following line doesn't (resulting in undefined):
console.log($rootScope.wg.variable+1);
I've experimented with different syntax options but haven't been able to find one that works correctly yet.
To achieve the desired outcome, it is essential to approach it differently:
console.log($rootScope.wg["variable" + 1]);
The significance lies in understanding that variable1 differs from variable+1. While this distinction may not be specific to AngularJS, it underscores the fundamental principles of concatenation logic in JavaScript and other programming languages.
This process involves accessing the key of an object, with $rootScope.wg serving as the object referenced in the query.
One way to access an object is by using its key. The key can be combined as a string, as shown in the example below.
console.log($rootScope.wg['variable' + 1]);
