+# no-pipeline-operator
+
+This prevents the use of the Pipeline Operator
+
+```js
+const result = "hello" |> capitalize |> exclaim
+```
+
+These will not be allowed because they are not supported in the following browsers:
+
+ - Edge (any version at the time of writing)
+ - Safari (any version at the time of writing)
+ - Firefox (any version at the time of writing)
+ - Chrome (any version at the time of writing)
+
+## What is the Fix?
+
+For simple expressions you can wrap each function inside the previous pipeline call:
+
+```js
+// these are equivalent:
+const result = "hello" |> capitalize |> exclaim
+const result = exclaim(capitalize("hello"))
+```
+
+Lastly, you could consider using a utility function such as [lodash' `_.flow`](https://lodash.com/docs/4.17.15#flow) or [`_.flowRight`](https://lodash.com/docs/4.17.15#flowRight)
+
+```js
+const result = _.flow(capitalize, exclaim)("hello")
+const result = _.flowRight(exclaim, capitalize)("hello")
+```
+
+This can be safely disabled if you intend to compile code with the `@babel/plugin-proposal-pipeline-operator` Babel plugin.
