API

Deep-merge b into a.

• a any: Destination value
• b any: Source value

  • arrayExtend boolean or string[]: Whether to extend arrays instead of replacing them. When passed a string array, it will only extend the object keys provided in that array.
  • maxRecursion number: Amount of nesting levels to recurse into. Default: 20
