Utilizing the .then() method allows your code to run asynchronously after the previous code has finished, without blocking. For example:
somethingThatTakesAWhile().then(()=>{console.log("A"})
console.log("B");
The output in this case will be:
B
A
To improve readability and functionality, make your function asynchronous and replace the then syntax with the await keyword as shown below:
async function getLatLng(location) {
let response = await fetch(...);
let data = await response.json();
let coordinates = {lat: data..., lng: data...}
return coordinates;
}
For a better understanding of promises and asynchronous code, refer to Mozilla's guide.
