About using Javascript

Hi there, I would like to ask your thoughts about using JavaScript. In my team, we often use JavaScript to meet the customers demand. But, I have some concerns about using a lot of JavaScript. I wonder if too much JavaScript code will spoil the merits of Mendix. Is there nothing we can do about it? Does anyone have similar concern? If there are, what do you think for a solution? Thanks in advance, Satomi

I agree with Duc, if your team is able to develop high quality widgets there's little risk. Obviously building custom widgets means you will have to think about delivering support on your widget. 

If, instead of building widgets, you use a lot of HTML/JS snippets your apps might run into performance issues.
