DevExtreme JavaScript - Tips & Tricks (September - October 2020)

Due to the number of interesting support tickets we collected over the last couple of months, we decided to publish separate tips & tricks posts for Angular, React, and Vue. This post covers topics that apply to JavaScript generally – so its content will be helpful to those targeting jQuery, Angular, React, and Vue. 

As always, we’re here to help. Should you have any questions about this content, feel free to post your feedback in the comment section below.
