Script Preparation code:

window.str1 = '1';
window.str2 = '2';
window.arr1 = ['cat', 'dog', 'bird'];
window.arr2 = ['cat', 'dog', 'bird'];
window.obj1 = { a: 1, b: 2, c: window.arr1 };
window.obj2 = { a: 3, b: 4, c: window.arr2 };

Tests:

_.isEqual for string
_.isEqual(window.str1, window.str2)
JSON.stringify for string
JSON.stringify(window.str1) === JSON.stringify(window.str2);
_.isEqual for array
_.isEqual(window.arr1, window.arr2)
JSON.stringify for array
JSON.stringify(window.arr1) === JSON.stringify(window.arr2);
_.isEqual for object
_.isEqual(window.obj1, window.obj2)
JSON.stringify for object
JSON.stringify(window.obj1) === JSON.stringify(window.obj2);
