示例1: eachArrayValueMutation

const diffCSSGroupingRuleChildren = (oldRule: SlimCSSGroupingRule, newRule: SlimCSSGroupingRule, path: any[]) => {
  const diffs: Mutation<any[]>[] = [];

  eachArrayValueMutation(
    diffArray(oldRule.rules, newRule.rules, compareCSSRules),
    {
      insert({ index, value }) {
        diffs.push(createInsertChildMutation(CSS_INSERT_RULE, path, compressRootNode(value), index));
      },
      delete({ index }) {
        diffs.push(createRemoveChildMutation(CSS_DELETE_RULE, path, null, index));
      },
      update({ newValue, originalOldIndex, index, patchedOldIndex }) {
        if (index !== patchedOldIndex) {
          diffs.push(createMoveChildMutation(CSS_MOVE_RULE, path, null, index, patchedOldIndex));
        }
        diffs.push(
          ...diffCSSRule(
            oldRule.rules[originalOldIndex],
            newValue,

示例2: diffArray

export const diffParentNode = (oldNode: BasicParentNode, newNode: BasicParentNode, diffChildNode: (oldChild: BasicNode, newChild: BasicNode) => Mutation<any>[]) => {

  const mutations = [];

  const diff = diffArray(Array.from(oldNode.childNodes), Array.from(newNode.childNodes), (oldNode, newNode) => {
    if (oldNode.nodeName !== newNode.nodeName || oldNode.namespaceURI !== newNode.namespaceURI) return -1;
    return 1;
  });
  
  eachArrayValueMutation(diff, {
    insert({ index, value }) {
      mutations.push(createParentNodeInsertChildMutation(oldNode, value, index));
    },
    delete({ index }) {

    },
    update({ originalOldIndex, patchedOldIndex, newValue, index }) {

        mutations.push(createParentNodeMoveChildMutation(oldNode, oldNode.childNodes[originalOldIndex], index, patchedOldIndex));
      }
      const oldValue = oldNode.childNodes[originalOldIndex];
      mutations.push(...diffChildNode(oldValue, newValue));
    }
