Import local GeoJSON file into Leaflet

I just used a leaflet. From the geoJSON demo page I saw if you want to include data you have to use
<script src="data/us-states.geojson"></script>
and if you open the files looks like
var ustates = {
"type": "FeatureCollection",
......
};
and if you want to call them use
var data = [ustates] ;
Is there another way to call the data?
The geojson file that I have has no initial variable and looks like this:
{
"type": "FeatureCollection",
......
}
I have lots of data and I have to open 1 by 1 to add variable on geojson data so I mean can I just call the data like
var ustates = <?php include "data/us-states.geojson"; ?>
var data = [ustates];

We use this function in our project (credits go to Roberto MF):
function fetchJSON(url) {
return fetch(url)
.then(function(response) {
return response.json();
});
}
It uses the Fetch API to download the file. You can simply use your path data/us-states.geojson as url. Example with your data:
var data = fetchJSON('data/us-states.geojson');
Be aware that this doesn't work in Internet Explorer by default, but you can polyfill it by adding this line to your HTML-<head>:
<script src="https://bowercdn.net/c/fetch-1.0.0/fetch.js" integrity="sha384-j9GCh0V617Ks+uEOZnAhwzTOWu5lPIlPW3QYRSfEwXd+x7VqP1XHNLgj3AIX7Mo0" crossorigin="anonymous"></script>

Very similar to the previous answer we use XHR to get the file and load the data into Leaflet.
const xhr = new XMLHttpRequest();
xhr.open('GET', 'data/us-states.geojson');
xhr.setRequestHeader('Content-Type', 'application/json');
xhr.responseType = 'json';
xhr.onload = function() {
if (xhr.status !== 200) return
L.geoJSON(xhr.response).addTo(map);
};
xhr.send();
