Tax Rate: {{$number tax_rate "0%"}}

Bad:

Tax Rate: {{$number tax_rate "0%"}}

{{$var "tax_rate" 0.07}} //Variable is declared after it is used

Example #2 - Advanced

Template

Create a custom variable and set the value to the results of the filter function where we filter items that have a quantity of 10 or more.

Repeat the section for each item in the custom variable

Data

{
  "items":[
    {
      "name": "Item #1",
      "qty": 5
    },
    {
      "name": "Item #2",
      "qty": 10
    },
    {
      "name": "Item #3",
      "qty": 15
    },
    {
      "name": "Item #4",
      "qty": 20
    }
  ]
}

Result

Variables can only be accessed after the point in the template where they are declared.
