v2.7.1

• Fix: allow dynamic minCost function call on chunkedByCost, for dynamic cost functions that change over time.
• Packaging fix: no longer trigger pnpm's "Ignored build scripts" warning in consumer projects.

v2.7.0

• New custom helper: chunkedByCost(items, costOf, maxCost, minCost?), groups a stream of items into chunks bounded by a hard maxCost cap and an optional minCost soft target.
• Drop support for Node 20.x (it probably still works, but it's EoL)

v2.6.0

• Add new xrange, which is like range but returns an array directly instead of an iterable.

v2.5.0

• New itertools: groupBy and indexBy
• Renamed groupby to igroupby
• Deprecated groupby (now an alias to igroupby)
• Drop support for Node 18.x (it probably still works, but it's EoL)

v2.4.1

• Use bundler module resolution setting (recommended setting for libraries that use a bundler)
• Upgrade dev dependencies

v2.4.0

• Add second param index to all predicates. This will make operations like partitioning a list based on the element position as easy as partitioning based on the element value, for example:

  const items = [1, 2, 3, 4, 5, 6, 7, 8, 9];
  const [thirds, rest] = partition(items, (item, index) => index % 3 === 0);
  console.log(thirds); // [1, 4, 7]
  console.log(rest); // [2, 3, 5, 6, 8, 9]

• Officially drop Node 16 support (it may still work)

v2.3.2

• Fix missing top-level exports for izipLongest3 and intersperse

v2.3.1

• Actually export the new itertool at the top level

v2.3.0

• Add new dupes(iterable, keyFn?) function, which returns groups of all duplicate items in iterable.

v2.2.5

• Add missing export for repeat
