Limit items in a .map loop
I would like to ask how can I limit my .map loop for example to a 5 items only because currently when I access an api it returns 20 items. but I want to display only 5. Mostly that I found is just looping all throughout the array of objects and not limiting it to a number of items.
Note: I have no control on the API because I'm just using the moviedb api
Here's my code:
var film = this.props.data.map((item) => {
return <FilmItem key={item.id} film={item} />
});
return film;
Answers:
You could use Array#slice and take only the elements you need.
var film = this.props.data.slice(0, 5).map((item) => {
return <FilmItem key={item.id} film={item} />
});
return film;
If you do not neet the original array anymore, you could mutate the array with seting length to 5 and iterate then.
