Js Code optimization record by bit _ javascript tips-js tutorial

This project has a function. switch statements are frequently used. During code optimization, replace them with arrays. 1. Simple Example:
Switch case

The Code is as follows:

Var caseContent = ''; // content after condition judgment
Var caseValue = 5; // condition judgment Value
Switch (caseValue ){
Case 0:
CaseContent = "Shoes ";
Break;
Case 1:
CaseContent = "Pants ";
Break;
Case 2:
CaseContent = "coat ";
Break;
......
Case 5:
CaseContent = "hat ";
Break;
Default:
CaseContent = "casual ";
Break;
}

Array use case

The Code is as follows:

Var caseContent = ''; // content after condition judgment
Var caseValue = 5; // condition judgment Value
Var caseContentArr = ["Shoes", "Pants", "coat"..., "Hats"];
CaseContent = caseContentArr [caseValue]? CaseContentArr [caseValue]: "casual ";

2. Advantages and Disadvantages Analysis
The code in array mode is concise and efficient, but the readability is not as good as switch case.
