Syntax

{{ value | sum }}{{ value | sum:"amount" }}{{ value | sum:"details.amount" }}

Usage

  • Without a parameter, numeric array items are added.
  • Pass a quoted property path to add values from object items. Dotted paths select nested own properties.
  • Finite numbers and nonblank numeric strings are included. Missing properties, blank strings, nonnumeric values, and infinities are ignored.
  • An empty array returns 0.
