Is any better syntax to perform this code? : <p>Below is my code</p>

<pre><code>    if(!chineseName) {
        alert("chineseName is not correct");
    }
    else if(!IDN){
        alert("IDN is not correct");
    }
    else if(!mobileNumber){
        alert("number is not correct");
    }
    else if(hasAccount){
        if(!isAccountNumberValid) {
            alert("account number is not correct");
        }
        else {
            check();
        }
    }
    else {
        check();
    }



    function check() {
        if(!check1 &amp;&amp; !check2) {
            alert("Please read NOTE and check the read box.");
        }
        else {
            alert("Everything is good to go!!");
        }
    }
</code></pre>

<p>Now, this code is working correct.
However, I would like to know if there any better syntax to perform same thing?</p>

<p>Thanks.</p>
