You can replay scenarios from tools like Selenium which are simulating real users. Neoload and jMeter, as Julius said, are simulating requests sent from browser to test backend of your application, but they are not actually loading page with JS execution at all.

As far as I know JMeter does not run the browser, but just simulates http requests. That means you don't get any DEM functionality including session replay for sessions run from JMeter.
