+ * Returns the index of the first element of the list which matches the

+ * Acts as a transducer if a transformer is given in list position.

+ * @func
+ * @memberOf R
+ * @since v0.1.1
+ * @category List
+ * @sig (a -> Boolean) -> [a] -> Number
+ * @param {Function} fn The predicate function used to determine if the element is the
+ * desired one.
+ * @param {Array} list The array to consider.
+ * @return {Number} The index of the element found, or `-1`.
+ * @see R.transduce, R.indexOf

+ *
+ *      const xs = [{a: 1}, {a: 2}, {a: 3}];
+ *      R.findIndex(R.propEq('a', 2))(xs); //=> 1
+ *      R.findIndex(R.propEq('a', 4))(xs); //=> -1
