# JSONPath template syntax
|
||||||
|
|
||||||
|
JSONPath template is composed of JSONPath expressions enclosed by {}.
|
||||||
|
And we add three functions in addition to the original JSONPath syntax:
|
||||||
|
|
||||||
|
1. The `$` operator is optional since the expression always start from the root object by default.
|
||||||
|
2. We can use `""` to quote text inside JSONPath expression.
|
||||||
|
3. We can use `range` operator to iterate list.
|
||||||
|
|
||||||
|
|
||||||
|
The result object is printed as its String() function.
|
||||||
|
|
||||||
|
Given the input:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"kind": "List",
|
