AngularJS | json Filter
The json filter in AngularJs is used to convert a JavaScript object into a JSON. string.JavaScript object that we are using can be of any kind of JavaScript Object.
Syntax:

Where json is used to specifies that object should be displayed in JSON format and spacing is an optional parameter with default value 2 that specifies the number of spaces per indentation.
