Tests:

Lodash merge
var a = { a: 'foo', b: 'bar' }; var b = { c: 'foobar' }; var c = _.merge(a, b);
object.assign
var a = { a: 'foo', b: 'bar' }; var b = { c: 'foobar' }; var c = Object.assign(a, b);
spread
var a = { a: 'foo', b: 'bar' }; var b = { c: 'foobar' }; var c = { ...a, ...b };
spread mutate
var a = { a: 'foo', b: 'bar' }; var b = { c: 'foobar' }; a = { ...a, ...b };
