When you are defining an object, you can use the : notation for defining values of properties.

var obj = { test: "value" };

The = operator is used for defining variable values. As in the above example the variable obj is equal to that object.

Pay attention that you can define object properties also using the = operator.

var obj = {};
obj.test = "value";

Or

obj["test"] = "value";
