here some utils:

Code:

var IsNumeric = function(input) {
    return (input - 0) == input && (''+input).trim().length > 0;
};

Code:

var ReturnUser = function(text) {
    if(IsNumeric(text)) {
        return $players[text];
    } else {
        let found = [];
        for(let player of $players) {
            if(player.name.indexOf(text) != -1) {
                found.push(player);
            }
        }
        return found.length == 1 ? found[0] : found;
    }
};

example usage for ReturnUser:

Code:

$server.on("PlayerCommandText", function(player, text){ 
    let args = text.split(' '); 
    let cmd = args.shift(); 

    switch(cmd) {
        case '/pm': { 
            if(isNaN(args[0])){ 
                SendClientMessage( player, -1, "/pm [playerid/Part of Name] [message]"); 
                return 1;   
            }

            let arg1 = args.shift();
            let target = ReturnUser(arg1);

            if(!target) {
                return player.message(-1, "Couldn't find " + arg1);
            }
            if(Array.isArray(target)) {
                return player.message(-1, "Found matches: " + _.pluck(target, "id").join(", ")); // include underscore.js
            }
            
            msg = args.join(' '); 
            SendClientMessage(target.id, -1, `PM from ${player.name}: ${msg}`); 
            return 1; 
        } 
              
    } 
    return 0;
});
