Parameters

EXPRESSION {Literal Expression|KeyLookup Expression|Hash Expression|Call Expression|Helper Expression}:

Use

A call expression calls a function looked up in the scope followed by the helpers scope. It looks like:

Template:
    <h1>{{pluralize(type,ages.length)}}</h1>

Data:
    {
      pluralize: function(type, count){
        return type+(count === 1 ? "" : "s")
      },
      todos: new List([22,32,42]),
      type: "age"
    }

Result:
    <h1>Ages</h1>

Call expression arguments are comma (,) separated. If a Hash expression is an argument, an object with the hash properties and values will be passed. For example:

Template:
    <h1>{{pluralize(word=type count=ages.length)}}</h1>

Data:
    {
      pluralize: function(options){
        return options.word+(options.count === 1 ? "" : "s")
      },
      todos: new List([22,32,42]),
      type: "age"
    }

Result:
    <h1>Ages</h1>
