587d7fb5367417b2b2512c03	Use the Caret-Character to Use the Latest Minor Version of a Dependency	2	301531

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.

"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.

Tests

tests:
  - text: '"dependencies" should include "moment"'
    testString: '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); })'
  - text: '"moment" version should match "^2.x.x"'
    testString: '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); })'
