// Clone
util.common.clone({a: {b: "c"}, b: ["a"]});
// console.log: { a: { b: 'c' }, b: [ 'a' ] }

// Equivalent to verify
util.common.equal(1, 2);
// console.log: false
util.common.equal(2, 2);
// console.log: true
util.common.equal('abc', 'ab');
// console.log: false
util.common.equal('abc', 'abc');
// console.log: true
util.common.equal(['abc'], ['abc', 'abc']);
// console.log: false
util.common.equal(['abc'], ['abc']);
// console.log: true
const x = {a: {b: "c"}, b: ["a"]}, y = {a: {b: "c"}, b: ["a"]}, z = {a: {b: "c"}, b: ["a", "b"]};
util.common.equal(x, y);
// console.log: true
x === y;
// console.log: false
util.common.equal(x, z);
