好的，所以最近我想制作一个setup.js来编写我的config.json，但是idk为什么它会有一个错误。

我不知道js是怎么工作的

我的代码是

const rl = require("readline-sync");
const fs = require("fs");
let none = " change this crack to password if u wanna use premium account";
let ip,
    user,
    pass;
    
ip = rl.question("Enter the server that the bot will run on: ");
user = rl.question("Enter the MC account email/username: ");
pass = rl.question(' is your minecraft account crack ? ', {
  trueValue: ['yes'],
  falseValue: ['no']
});
if (pass === true) {
    let cracka = true;
        console.log("ok minecraft account setted to crack")
    } else if (pass === false) {
        let cracka = false;
        rl.question("Enter the MC account password: ");
    } else {
        console.log('Sorry. What does "' + pass + '" you said mean?');
    }

console.clear();
console.log("Server: " + ip);
console.log("User: " + user);
console.log("Password: " + pass);
if (rl.keyInYNStrict("Is this ok? ")) {
    console.clear();
    fs.writeFileSync(
        "config.json",
        JSON.stringify({
            
            server: ip,
            
            username: user,
            
        if (cracka = true) {
                crack: none,
        } else if (cracka = false) {
                password: pass,
        }
    })
);
    rl.keyInPause("File created. You now can run the program.");
} else {
    rl.keyInPause("OK. Cancelling...");
}

错误是

}else if (cracka = false) {
^
