Theres one more thing were going to cover before you know enough React basics to be able to move on to a real project, and thats how to loop over an array to render its contents.For every item in the array, it gives us the item itself in person and the position of the item in index. Notice how the following render function is able to accomodate arrays of all sizes. This is due to rendering in a list of React Elements created from the list of numbers coming in from the props.this.props.list.map(function(listValue). I cant seem to get this, or anything similar to work in a JSX React.js component. Instead I had to do the following, first building a temp array to the correct length and then looping the array.return (
this.props.level.map((item, index) > ( <. span classNameindent key index /> )). What you need to map your array of objects and remember that every item will be an object, so that you will use for instance dot notation to take the values of the objectmap( ( anObjectMapped, index ) > return
anObjectMapped.name - anObjectMapped.email
). React mapping multiple arrays.
