Guidelines and General Direction for Standard Library Proposals

[Michał Wadas]

My thoughts: big source of JavaScript criticism is its small standard
library and community attempts to solve that issue - hundreds of small
modules. Significant part of lodash should be present in standard library.
My lodash selection - chunk, dropWhile, first, last, flatten, fromPairs,
pull, without, takeWhile, zip, flatMap, keyBy, property, groupBy,
partition, sample, shuffle, sortBy, ary, memoize, once, operators as
functions, clamp, inRange, get, mapKeys, mapValues, pickBy, many strings
operations, attempt, constant, flow, noop, range.
