Script Preparation code:

function patchCustomizer(objValue, srcValue) {
  if (_.isArray(objValue)) {
    return srcValue;
  }
};

function patch(object, patch) {
  return _.mergeWith(object, patch, patchCustomizer);
};

function patchCopy(object, patch) {
  return _.mergeWith({}, object, patch, patchCustomizer);
};

var x = {
 a: {
   b: 1,
   c: 2,
   d: 3,
   j: {
     k: [1,2,3],
     l: [4,5,6]
   },
 },
 e: [1,2,3,4,5,6],
 f: 1,
 g: {
   h: 1,
 }
}

var y = {
 a: {
   j: {
     k: [1,3]
   },
 },
 e: [1],
 f: 2,
}

Tests:

patch(cloneDeep(x), y)
const a = patch(_.cloneDeep(x), y)
patchCopy(x, y)
const a = patchCopy(x, y)
ES6 spread (doesn't produce the expected output, just for performance reference)
const a = { ...x, ...y }
ES6 Object.assign (doesn't produce the expected output, just for performance reference)
const a = Object.assign({}, x, y)
