Experiences gained by developing this project

1. React : Project is developed using React as the main focus.

• Great understanding of working with states and props.
• Writing class/function compoenents.
• Working with stateful/stateless components.
• Writing more stateless components and less stateful components (makes module easily reusable)
• Lifecycle methods like compoenentDidMount,componentWillUnmount.
• Event listeners to create an interactive user experience.
• Rendering of specific components based on states.
• Inline conditional rendering where a single element(rather than component) is to be rendered depending on state.
• Working with arrays/objects methods like map,findIndexOf,forEach.
• Writing in JSX.
• Updating the state immutabily.
• Use of promises.

2. webRTC : This open-source project is used to capture and stream the audio/video media during the call. Once a connection is established it is also used to exchanges text data and also files.

• Capture data from media devices like audio/video
• Creating a peerConnection
• Creating a offer/answer
• Adding offer to description(local/remote)
• Sending offer/answer to peer
