# --description--
|
|
|
|
Similar to how the tilde we learned about in the last challenge allows npm to install the latest PATCH for a dependency, the caret (`^`) allows npm to install future updates as well. The difference is that the caret will allow both MINOR updates and PATCHes.
|
|
|
|
Your current version of moment should be "~2.10.2" which allows npm to install to the latest 2.10.x version. If you were to use the caret (^) as a version prefix instead, npm would be allowed to update to any 2.x.x version.
|
|
|
|
```json
|
|
"package": "^1.3.8"
|
|
```
|
|
|
|
This would allow updates to any 1.x.x version of the package.
|
|
|
|
# --instructions--
|
|
|
|
Use the caret (`^`) to prefix the version of moment in your dependencies and allow npm to update it to any new MINOR release.
|
|
|
|
**Note:** The version numbers themselves should not be changed.
|
|
|
|
# --hints--
|
|
|
|
"dependencies" should include "moment"
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/package.json').then(
|
|
(data) => {
|
|
var packJson = JSON.parse(data);
|
|
assert.property(
|
|
packJson.dependencies,
|
|
'moment',
|
|
'"dependencies" does not include "moment"'
|
|
);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
|
|
|
|
"moment" version should match "^2.x.x"
|
|
|
|
```js
|
|
(getUserInput) =>
|
|
$.get(getUserInput('url') + '/_api/package.json').then(
|
|
(data) => {
|
|
var packJson = JSON.parse(data);
|
|
assert.match(
|
|
packJson.dependencies.moment,
|
|
/^\^2\./,
|
|
'Wrong version of "moment". It should be ^2.10.2'
|
|
);
|
|
},
|
|
(xhr) => {
|
|
throw new Error(xhr.responseText);
|
|
}
|
|
);
|
|
```
