I am working with Javascript(ES6) /FaceBook react and trying to get the first 3 elements of an array that varies in size. I would like do the equivalent of Linq take(n).
In my Jsx file I have the following:
var items = list.map(i => { return ( <myview item={i} key={i.id} /> ); });
Then to get the first 3 items I tried
var map = new Map(list); map.size = 3; var items = map(i => { return (<SpotlightLandingGlobalInboxItem item={i} key={i.id} />); });
This didn’t work as map doesn’t have a set function.
Can you please help?

I believe what you’re looking for is:
// ...inside the render() function var size = 3; var items = list.slice(0, size).map(i => { return <myview item={i} key={i.id} /> }); return ( <div> {items} </div> )
