Usage

deeplyAssign

// simple case
const simpleData = { count: 1 };
const simpleSourceOne = { foo: 'bar' };
const simpleSourceTwo = { bar: 'baz', count: 3 };

const simpleResult = deeplyAssign(simpleData, sourceOne, )
console.log(JSON.stringify(simpleResult, null, 4));
// { foo: 'bar', bar: 'baz', count: 3 }
