/*
 * SplitChunksPlugin is enabled by default and replaced
 * deprecated CommonsChunkPlugin. It automatically identifies modules which
 * should be splitted of chunk by heuristics using module duplication count and
 * module category (i. e. node_modules). And splits the chunks…
 *
 * It is safe to remove "splitChunks" from the generated configuration
 * and was added as an educational example.
