First, the concept of design patterns
Design patterns are highlighted structural design codes and problem-solving ideas
Second, the strategy pattern
Strategy Mode: All the solutions we should be set up in advance, do not judge according to what is happening today, the different problems and different solutions correspondence.
The greatest advantage of the policy is to model problems and solutions do the treatment mappings, so you do not need to judge each
In simple terms we normally Monday, Tuesday, Wednesday morning shift need to get up at 7 every Thursday, 10:00 on Friday Intermediate to get up every day, we would have booked using a mobile phone alarm clock early, the phone will be based on the current Some date to determine the alarm sounded, this is the simplest strategy mode
Third, the case
LoL = {var
Hero: {
"blind monk": function () {
},
"Yasuo": function () {
},
"Triticum": function () {
}
},
Create: function (type) {
// ? What is here to fill
}
}
LoL.create ( "blind monk");
Think about how we get the hero of this object type by type?
Our first thought is to switch judgment, but the correct answer is to return new this.hero [type] ();
This reduces the determination logic of the code, the code efficiency will improve
