About Swtich Statments in JavaScript

Question

I write this code to try my idea and is working fine :

 var answer = prompt("Please type your gender? male / female"); var gender = answer; switch (gender) { case "female": console.log("Hello, madame!"); break; case "male": console.log("Hello, sir!"); break; default: console.log("Hello!"); } 

But the problem for example when someone add answer with uppercase like " MALE " or Capital Letter like " Male " so this code is not working. any idea about that to get working in any statments of words ( Lowercase / Uppercase / Capital Letter )

Answer 1

将输入转换为小写：

switch (gender.toLowerCase()) {

Answer 2

Use

var gender = answer.toLowerCase();

Also, please indent your code in future.
