Added handling for `onerror` to log on the `error` stream of the console by default, maybe not the best possible behavior, but good for starters. If you have a better idea for this, please change it accordingly.

### httpGet
|
|
|
|
Makes a `GET` request to the passed URL.
|
|
|
|
Use `XMLHttpRequest` web api to retrieve data from the given `url`.
|
|
Handle the `onload` event, by running the provided `callback` function.
|
|
Handle the `onerror` event, by running the provided `err` function.
|
|
Omit the third argument, `err` to log the request to the console's error stream by default.
|
|
|
|
```js
|
|
const httpGet = (url, callback, err = console.error) => {
|
|
const request = new XMLHttpRequest();
|
|
request.open("GET", url, true);
|
|
request.onload = () => callback(request);
|
|
request.onerror = () => err(request);
|
|
request.send();
|
|
}
|
|
```
|
|
|
|
```js
|
|
httpGet('https://jsonplaceholder.typicode.com/posts', request => {
|
|
console.log(request.responseText);
|
|
}) // 'Array of 100 items'
|
|
```
