Compare primitives the right way (using
<
,>
and==
)
This module does the right thing with numbers and ascii strings.
Normally String.prototype.localeCompare
is recommended for strings,
but that can have nasty side effects on some machines, eg.
'cu'.localeCompare('cs', 'hu')
Compare the above in stock node (which doesn't come with Intl
) and
a browser of your choice (which most likely has Intl
support).
var compare = require('compare')
[1, 2, 10].sort() // [1, 10, 2]
[1, 2, 10].sort(compare) // [1, 2, 10]
// Below is sorted correctly according to Hungarian, but runtimes without Intl
// support will reorder them
['cu', 'cs'].sort((a, b) => a.localeCompare(b, 'hu'))
['cu', 'cs'].sort(compare) // This will always sort the same
Standard Array.prototype.sort(cmp)
function signature. If a > b
return 1
,
if a < b
return -1
, otherwise return 0
Thanks to hughsk
for the npm name!
