In PHP and other languages there are ways to suppress error/warning messages.
Is there a way in javascript or jquery to prevent errors and warnings from being writte
After doing some research and development for this problem, I came across this solution which will hide warnings/Errors/Logs as per your choice.
(function () {
    var origOpen = XMLHttpRequest.prototype.open;
    XMLHttpRequest.prototype.open = function () {        
        console.warn = function () { };
        window['console']['warn'] = function () { }; // For confirmation again
        this.addEventListener('load', function () {                        
            console.warn('Something bad happened.');
            window['console']['warn'] = function () { };
        });        
    };
})();
Add this code before JQuery plugin (e.g /../jquery.min.js) even as this is JavaScript code that does not require JQuery. Because some warnings are in JQuery itself.
