- ## API
- #### `caniuse.getSupport(feature)`
- _ask since which browsers versions a feature is available_
- * `y`: Since which browser version the feature is available
- * `n`: Up to which browser version the feature is unavailable
- * `a`: Up to which browser version the feature is partially supported
- * `X`: Up to which browser version the feature is prefixed
- ```js
- caniuse.getSupport('border-radius', true)
- /*
- [ safari: { y: 3.1, x: 4 },
- opera: { n: 10, y: 10.5 },
- ios_saf: { y: 3.2, x: 3.2 },
- ie_mob: { y: 10 },
- ie: { n: 8, y: 9 },
- firefox: { a: 2, x: 3.6, y: 3 },
- chrome: { y: 4, x: 4 },
- and_chr: { y: 39 } ]
- */
- ```
- #### `caniuse.isSupported(feature, browsers)`
- _ask if a feature is supported by some browsers_
- ```js
- caniuse.isSupported('border-radius', 'ie 8, ie 9') // false
- caniuse.isSupported('border-radius', 'ie 9') // true
- ```
- #### `caniuse.find(query)`
- _search for a caniuse feature name_
- Ex:
- ```js
- caniuse.find('radius') // ['border-radius']
- caniuse.find('nothingness') // []
- caniuse.find('css3')
- /*
- [ 'css3-boxsizing',
- 'css3-colors',
- 'css3-cursors-newer',
- 'css3-cursors',
- 'css3-tabsize' ]
- */
- ```
- #### `caniuse.getLatestStableBrowsers()`
- _get the current version for each browser_
- ```js
- caniuse.getLatestStableBrowsers()
- /*
- [ 'safari 8',
- 'opera 26',
- 'ios_saf 8.1',
- 'ie_mob 11',
- 'ie 11',
- 'firefox 33',
- 'chrome 39' ]
- */
- ```
- #### `caniuse.getBrowserScope()`
- _returns a list of browsers currently used for the scope of operations_
- ```js
- caniuse.getBrowserScope()
