Function createMapping

createMapping<Source, Target>(
    getSourceKey: (source: Source) => string | number,
    createResult: (source: Source, index: number) => Target,
    updateResult: (source: Source, target: Target, index: number) => void,
): Mapping<Source, Target>
Creates a Mapping instance that keeps an array of result objects synchronized with an array of source objects. See Working with arrays.
Type Parameters
- Source
  The type of source items. A database-record for instance.
- Target
  The type of target items. A MaquetteComponent for instance.
Parameters
- getSourceKey: (source: Source) => string | number
  function(source) that must return a key to identify each source object. The result must either be a string or a number.
- createResult: (source: Source, index: number) => Target
  function(source, index) that must create a new result object from a given source. This function is identical to the callback argument in Array.map(callback).
- updateResult: (source: Source, target: Target, index: number) => void
  function(source, target, index) that updates a result to an updated source.
Returns Mapping<Source, Target>
