What about “enter()” and “exit()” selection in d3.js?

Question Posted / princy singh


What about “enter()” and “exit()” selection in d3.js?..

Answer / Ayan Kantha

In D3.js, enter() is used to select all new nodes that should be added to the DOM, while exit() is used to select all existing nodes that should be removed. This makes it easy to update data-driven visualizations by adding or removing elements as necessary.
