# common-ancestor-path
|
||
|
|
|
||

const ancestor = require('common-ancestor-path')
|
||
|
|
|
||
|
|
// output /a/b
|
||
|
|
console.log(ancestor('/a/b/c/d', '/a/b/x/y/z', '/a/b/c/i/j/k'))
|
||
|
|
|
||
|
|
// normalizes separators, but NOT cases, since it matters sometimes
|
||
|
|
console.log(ancestor('C:\\a\\b\\c', 'C:\\a\\b\\x'))
|
||
|
|
|
||
|
|
// no common ancestor on different windows drive letters
|
||
|
|
// so, this returns null
|
||
|
|
console.log(ancestor('c:\\a\\b\\c', 'd:\\d\\e\\f'))
|

|
|
```
