blend(dest, src, combine)

If the "combine" option is true, then property prefixes: +, =, - and ? are used as modifiers describing how to combine source and destination property values.

  • param src Source object
  • combine Boolean. If true, then support key prefixes "+", "=", "-", "?" to add, assign and subtract and conditionally assign key values. When adding string properties, values will be appended using a space separator. Extra spaces will not be removed on subtraction. Arrays with string values may also be combined using these key prefixes. Defaults to false.
