For example, if the mark value is group: 1, put it in a group. The mark value is group: 2 is placed in a group, and then displayed in different modules on the front-end. How to traverse data? After traversing, how can we put different mark values into different arrays? Public static function buildList ($ module) {$ jobList2 = "";

simple inheritance relationship is as follows:‘use strict‘class Class1{ toString(){ return ‘parent class.‘; }}class SubClass extends Class1{ toString(){ return ‘sub class.‘; }}var sc = new SubClass();console.log(sc.toString()); // "sub class"Among them, SC is an example of Class1, and also an example of subclass:console.log(sc instanceof Class1); //trueconsole.log(sc instanceof SubClass); //trueWhat if you want to invoke the method of the parent class?class SubClass2 extends Class1{
