a.should.shallowDeepEqual(b);
expect(a).to.shallowDeepEqual(b);
assert.shallowDeepEqual(a, b);
`

Example

assert.shallowDeepEqual({
name: 'Michel',
language: 'javascript',
tags: [
'developer',
'gamer'
]},
{
name: 'Michel',
tags: [
'developer'
]}); // true

assert.shallowDeepEqual([
{brand: 'apple', color: 'red'},
{brand: 'samsung', color: 'blue'},
],
{
length: 2,
0: {color: 'red'},
1: {brand: 'samsung'},
}); // true

assert.shallowDeepEqual({
name: 'Michel',
age: undefined
},
{
name: 'Michel',
