Transform a string into an object using AngularJS $parse function

Imagine having a server that sends back a response in the form of:

{
    multiply:function(x,y) {
        return x*y;
    },
    divide:function(x,y) {
        return x/y;
    }   
}

Can this be converted into a functional method?

I attempted to convert it using:

$parse(element.Content) // Content represents the response string

however, I received the error:

Token '{' is an unexpected token

My goal is to achieve something like:

elementFunctions = $parse(element.Content)

$parse isn't as straightforward as you may think!

In essence, it simply resolves properties based on their names within a certain context (angular scopes) -- more or less.
But it goes beyond that, allowing interaction with these properties. You can grasp the concept by referring to its documentation.


It doesn't evaluate Strings like JavaScript code.

You're probably thinking of using eval on your string.
However, in most cases, there's a better, faster, and more controlled solution available!

const code = ''
+   'const functions = {'
+       'add: function(a,b) {'
+           'return a+b;'
+       '},'
+       'subtract: function(a,b) {'
+           'return a-b;'
+       '}'
+   '};'
+   'functions';

console.log(eval(code).add(50, 1));
