Remove jquery from JavaScript : I am new in the field of development, I develop an API with angularjs 2 using the janus media server, I have a problem with the start button, once I run my janus it starts the button automatically not manually , This is the function I used:

//   Use a button to start the demo
								$('#start').click(function() {
								if(started)
								return;
								started = true;
								$(this).attr('disabled', 
      'true').unbind('click');
								//  Make sure the browser supports WebRTC
								//   if(!Janus.isWebrtcSupported()) {
								//  Janus.log("No WebRTC support... ");
								  return; 
								// }
								 });
