Tests:

First lodash
_.isEqual(window.foo1, window.bar1)
First json
JSON.stringify(window.foo1) === JSON.stringify(window.bar1);
Second lodash
_.isEqual(window.foo2, window.bar2)
Second json
JSON.stringify(window.foo2) === JSON.stringify(window.bar2);
Third lodash
_.isEqual(window.foo3, window.bar3)
Third json
JSON.stringify(window.foo3) === JSON.stringify(window.bar3);
