     * toArray, transform, union, uniq, unset, unshift, unzip, values, where, without, wrap, and zip
     *
     * The non-chainable wrapper functions are:
     * clone, cloneDeep, contains, escape, every, find, findIndex, findKey, findLast,

     * Explicit chaining can be enabled by using the _.chain method.
