React component not re-rendering on state change

Question

I have a React Class that\'s going to an API to get content. I\'ve confirmed the data is coming back, but it\'s not re-rendering:

var DealsList = React.createCla         


        

Answer 1

I'd like to add to this the enormously simple, but oh so easily made mistake of writing:

this.state.something = 'changed';

... and then not understanding why it's not rendering and Googling and coming on this page, only to realize that you should have written:

this.setState({something: 'changed'});

React only triggers a re-render if you use setState to update the state.
