Script Preparation code:

// 1 level deep
window.foo1 = { a: 1, b: 2, c: { a: 1, b: 2, c: { a: 1, b: 2 } } };
window.bar1 = { a: 1, b: 3, c: { a: 1, b: 2, c: { a: 1, b: 2 } } };

// 2 levels deep
window.foo2 = { a: 1, b: 2, c: { a: 1, b: 2, c: { a: 1, b: 2 } } };
window.bar2 = { a: 1, b: 2, c: { a: 1, b: 3, c: { a: 1, b: 2 } } };

// 3 levels deep
window.foo3 = { a: 1, b: 2, c: { a: 1, b: 2, c: { a: 1, b: 2 } } };
window.bar3 = { a: 1, b: 2, c: { a: 1, b: 2, c: { a: 1, b: 4 } } };

Tests:

_.isEqual Level 1
_.isEqual(window.foo1, window.bar1)
JSON.stringify Level 1
JSON.stringify(window.foo1) === JSON.stringify(window.bar1);
_.isEqual Level 2
_.isEqual(window.foo2, window.bar2)
JSON.stringify Level 2
JSON.stringify(window.foo2) === JSON.stringify(window.bar2);
_.isEqual Level 3
_.isEqual(window.foo3, window.bar3)
JSON.stringify Level 3
JSON.stringify(window.foo3) === JSON.stringify(window.bar3);
