Explain JSON.stringify() in JavaScript

This video explains about JSON.stringify() in JavaScript.

**********************************************************

JSON.stringify() converts an object or array in a JSON string. It takes three arguments,

1. object or array
2. an optional function to replace output

3. an optional space value

*****************************************************
For an object's property JSON.stringify omits undefined values and converts NaN, null, Infinity to null

***************************************************

For an array value JSON.stringify converts undefined, NaN, null, Infinity to null

***********************************************************

You can pass second argument as replacer to replace the output with new value.
