The last piece of nonsense too much, write very rotten, this time to talk about inheritance, we know the last section of prototype, now I start from prototype to achieve the method

Occupation. prototype. Work =function (name) {
return name+ "work";
}
Occupation. prototype. =function () {
return "work";
