pairsToObject
Input a object array pairs, and return a plain object composed of key-value pairs extracted from each sub-array. Optional parameters getKey and getValue can be provided to transform the array elements into keys and values. If not provided, the first element of each sub-array (index 0) will be used as the key, and the second element (index 1) will be used as the value.
getKey and getValue can be field paths of getByPath or callback functions.
