How to get the Current logdin user using both client side and server side??

[SandeepKSingh]

I have a requirnmnet , on Incident Form caller should be autopopulated based on current logdin user in ServiceNow.

Can anyone help with code ?

Yes you can use g_user API in client script and gs.getUser() will work 
g_form.setValue('caller_id', g_user.userID);

@SandeepKSingh You can create an onLoad client script on the incident form to populate logged in user on the incident form.

function onLoad() {
    // Check if the form is new (to avoid changing the caller on existing incidents)
    if (g_form.isNewRecord()) {
        // Set the 'Caller' field to the logged-in user
        g_form.setValue('caller_id', g_user.userID);
    }
}

Please mark the solution helpful and accepted solution if it manages to address your question.

As you requested :-

PFB full script :-

function onLoad() {

if (g_form.isNewRecord()) {

if (!g_form.getValue('caller_id')) {

g_form.setValue('caller_id', g_user.userID);
}
}
}

You can you the above in case of Service Catalog also as in Service catalog we have variables which you can access based on catalog client script  and auto-populate current lodging user on the catalog form
