Prefer [R.flatMap] over consecutive [R.map] and [R.flat]

When using [R.map] and [R.flat], it can be more concise to use [R.flatMap] instead.

Rule Details

This rule takes no arguments.

The following patterns are considered warnings:

t = R.flat(R.map(a, f));

The following patterns are not considered warnings:

t = R.map(a, f);

t = R.flatMap(a, f);

When Not To Use It

If you do not want to enforce using [R.flatMap], and prefer [R.map] and [R.flat] instead, you should not use this rule.
