why prettier.semi not adding any semicolons on my JavaScript files?

This one of my files that prettier didn't add any semicolons but format it well,

function usercreate(name,score){
        this.name = name 
        this.score = score
        }
        usercreate.prototype.increment=function(){
            this.score++
            console.log(this.score)
        }
        usercreate.prototype.login=function(){
            console.log("loged in")
        }
    const user1=new usercreate("zahal",100)
    user1.increment()
    user1.login()
    const user2=new usercreate("sam",01)
    user2.increment()
    user2.login()

and this is my v-code setting.json

{
    "workbench.colorTheme": "Visual Studio Light",
    "security.workspace.trust.untrustedFiles": "open",
    "prettier.semi": true
}

and I don't use Eslint
