I know it may be a bit stupid, but why doesn't it works like this
.then(function(response) {
this.setState({
gifs: response.data.data,
loading: false
})
})
But works like this?
.then(response => {
this.setState({
gifs: response.data.data,
loading: false
})
})
The difference lays in the function syntax

So this.setState is going to break if you use the traditional function. This section of the MDN docs explains this concept in more detail.
