Solution 1:

You'll have to use bracket notation instead of dot notation:

myObject["myProp-"]

Solution 2:

var myObject = {"myProp-":"myValue", "foo": "bar" };

myObject.foo;
myObject["foo"]; // these are equivalent

myObject.myProp-; // syntax error
myObject["myProp-"]; // this is finevar key = "myProp-";
myObject[key]; // this works as well (dynamic index)
myObject.key; // undefined

Bracket notation are dot notation are equivalent.
