The
clone
method now accepts any type of input but also recursively perform a deep copy of the array items. Rewrite theconfigMerge
andscaleMerge
helpers which now rely on a new generic and customizablemerge
method, that one accepts a target object in which multiple sources are deep copied. Note that the target (first argument) is not cloned and will be modified after callingmerge(target, sources)
. Add amergeIf
helper which merge the source properties only if they do not exist in the target object.@chartjs/maintainers please review this PR carefully since it impacts the whole config process :)
