Examples

intersectDeep(objects...) => {Object}

Simple objects

const intersectDeep = require('intersect-deep');
intersectDeep({a: 1, b: 1},
              {a: 2, b: 2, c: 2},
              {a: 3}); // => {a: 3}

Complex objects (level more than 1)

intersectDeep(
    {
        a: 1,
        b: 1,
        c: {
            aa: 1,
            bb: 1
        }
    },
    {
        a: 2,
        b: 2,
        c: {
            aa: 2
        }
    },
    {
        a: 3,
        b: 3,
        c: {
            aa: 3,
            bb: 3,
            cc: 3
        }
    }
);

// {
//      a: 3,
//      b: 3,
//      c: {
//          aa: 3
//      }
// }

If not equal types? Ignore it! (focus on value of a)

intersectDeep(
    {
        a: 1,
        b: 1
    },
    {
        a: {
            aa: 2,
            bb: 2
        },
        b: 2
    }
);


// {
//    b: 2,
// }

intersectDeep(
	{
		a: 1,
		b: 1
	},
	{
		a: ['a', 'b'],
		b: 2
	}
);

// {
//    b: 2,
// }
