|
|
|
||
|

# example
|
||
|
|
|
||
|
|
``` js
|
||
|
|
var cmp = require('semver-compare');
|
||
|
|
var versions = [
|
||
|
|
'1.2.3',
|
||
|
|
'4.11.6',
|
||
|
|
'4.2.0',
|
||
|
|
'1.5.19',
|
||
|
|
'1.5.5',
|
||
|
|
'4.1.3',
|
||
|
|
'2.3.1',
|
||
|
|
'10.5.5',
|
||
|
|
'11.3.0'
|
||
|
|
];
|
||
|
|
console.log(versions.sort(cmp).join('\n'));
|
||
|
|
```
|
||
|
|
|
||
|
|
prints:
|
||
|
|
|
||
|
|
```
|
||
|
|
1.2.3
|
||
|
|
1.5.5
|
||
|
|
1.5.19
|
||
|
|
2.3.1
|
||
|
|
4.1.3
|
||
|
|
4.2.0
|
||
|
|
4.11.6
|
||
|
|
10.5.5
|
||
|
|
11.3.0
|
||
|
|
```
|
||
|
|
|
||
|
|
whereas the default lexicographic sort (`versions.sort()`) would be:
|
||
|
|
|
||
|
|
```
|
||
|
|
1.2.3
|
||
|
|
1.5.19
|
||
|
|
1.5.5
|
||
|
|
10.5.5
|
||
|
|
11.3.0
|
||
|
|
2.3.1
|
||
|
|
4.1.3
|
||
|
|
4.11.6
|
||
|
|
4.2.0
|
||
|
|
```

If the semver string `a` is greater than `b`, return `1`.

If the semver string `b` is greater than `a`, return `-1`.
|

|
|
If `a` equals `b`, return 0;
