Add a way to acceed to loop data

[bubbatls]

when using block {{#anArray}} {{/anArray}}
You may accedd to loop datas with @index @Arrayindex and @Length
{{@index}} / {{@Length}}
will output
1 / 12
2 / 12
3 / 12
...
@Arrayindex start at 0 instead of 1

Maybe there is a better way to do this, but something is really missing on this point

This looks like LOGIC

Nice 👍

Maybe a helper function/plugin.

Is there in spec?

[Arrayindex]

I am @Arrayindex

So, just out of curiosity, this branch only handles when the value is an object.

• Are there going to be unit tests that go along with this change?
• What would the side effects be when the value is truthy/falsy??

Example
Data :

{
  "booleanValue": true,    // true
  "stringValue": "Some String",    // true
  "emptyString": "",    // false
  "whiteSpace": "    ",    // true
  "numericFalseValue": 0,    // false
  "numericTrueValue": 1    // true
}

Template:

{{#booleanValue}} {{@index}} / {{@length}} {{/booleanValue}}
{{#stringValue}} {{@index}} / {{@length}} {{/stringValue}}
{{#emptyString}} {{@index}} / {{@length}} {{/emptyString}}
{{#whiteSpace}} {{@index}} / {{@length}} {{/whiteSpace}}
{{#numericFalseValue}} {{@index}} / {{@length}} {{/numericFalseValue}}
{{#numericTrueValue}} {{@index}} / {{@length}} {{/numericTrueValue}}

• How would this work with nested data??

Example
Data :

{
  employees : [
    {
      hasLeftCompany : false,
      firstName: "John"
    },
    {
      hasLeftCompany : true,
      firstName: "Jane"
    }
  ]
}

Template:

<table>
  <thead>
    <tr>
      <th colspan="2">Active Employees</th>
    </tr>
    <tr>
      <th></th>
      <th>First Name</th>
    </tr>
  </thead>
  <tbody>
    {{#employees}}
      {{^hasLeftCompany}}
        <tr>
          <td>{{@index}}</td>
          <td>{{fisrtName}}</td>
        </tr>
      {{/hasLeftCompany}}
    {{/employees}}  
  </tbody>
</table>
