window.foo = ['cat', 'dog', 'bird', {}, {a: 4, b: false, c: 'string', d: null}];
window.bar = ['cat', 'dog', 'bird', {}, {a: 4, b: false, c: 'string', d: null}];

 
window.foo = ['cat', 'dog', 'bird', {}, {a: 4, b: false, c: 'string', d: null}];window.bar = ['cat', 'dog', 'bird', {}, {a: 4, b: false, c: 'string', d: null}];
