7 # wildcard
8
9 Very simple wildcard matching, which is designed to provide the same
10 functionality that is found in the
11 [eve](https://github.com/adobe-webplatform/eve) eventing library.
12
13 ## Usage
14
15 It works with strings:
16
17 <<< examples/strings.js
18
19 Arrays:
20
21 <<< examples/arrays.js
22
23 Objects (matching against keys):
24
25 <<< examples/objects.js
26
27 ## Alternative Implementations
28
29 - <https://github.com/isaacs/node-glob>
30
31 Great for full file-based wildcard matching.
32
33 - <https://github.com/sindresorhus/matcher>
34
35 A well cared for and loved JS wildcard matcher.
