+
+> Rewrite [infer-partial-order](https://github.com/dominictarr/infer-partial-order) with TypeScript
+
+# Why rewrite
+
+* Rewriting makes me more aware of the author’s intentions
+* Adding a type declaration to the original module will not save much
+
+In order to understand of the function of the module, the following is the original README copied.
+
+# infer-partial-order
+
+infer the partial order of a set from a set of examples.
+
+say we have two sequences `A, B, C` and `B, A, C`.
+Here `A < C` and `B < C`, but sometimes `B == A`.
+This relationship is obvious, because there are only 3 items,
+but as the number of items increase, it's much less clear.
+
+## Example
+
+represent a partial ordering like this:
+``` ts
+import { infer } from '@jacobbubu/infer-partial-order'
+
+infer([ [A, B, C], [B, A, C] ])
+
+=> {
+  A:[],
+  B:[],
+  C:[A, B]
+}
+```
+
+Each key maps to the list of items that always come before it.
+
+for more complex cases, you might want to use the canonical mode,
+it strips out items that are indirectly lesser than a given item.
+This is still enough information to build a graph of the order
+relationships.
+``` js
+var infer = require('infer-partial-order')
+
+infer([ [A, B, C, D, E], [B, A, D, C, E], [A, B, C, D, E])
+
+=> {
+  A:[],
+  B:[],
+  C:[A, B],
+  D:[A, B],
+  E:[C, D]
+}
+```
