How to make a setter method in a module?

Question

Node.js

Good afternoon!

main.js file

const check = require("./test.js")
check("dh39dk")

test.js file

function checkToken(token) {
if(!arr[token]) return false
return true
}
module.exports = checkToken

How to make the main.js code look like this:

const check = require("./test.js")
check.setToken("dh39dk")
check()

Thanks in advance!

Answer 1

class TokenValidator {
    constructor(token) {
        this.token = token
    }

    check() {
       if (!arr[this.token]) return false
       return true
    }
}

const validator = new TokenValidator("dhejeuus")
console.log(validator.check())

Or (if you really want the setToken function)

class TokenValidator {
    setToken(token) {
        this.token = token
    }

    check() {
       if (!arr[this.token]) return false
       return true
    }
}

Well, and another option with a function prototype, but here already.
