+### Coalesce a set of arguments
+
+Use `find()` to return the first non excluded argument.
+
+```js
+const coalesce = (...args) => args.find(_ => ![undefined, null].includes(_))
+// coalesce(null,undefined,"",NaN, "Waldo") -> ""
+
+const coalesceFactory = (excludes = [null, undefined]) => (...args) => args.find(_ => !excludes.includes(_))
+// coalesceFactory([null, undefined, "", NaN])(undefined, null, NaN, "", "Waldo") -> "Waldo"
+```
