What is the Difference Between JSON.stringify and JSON.parse
Read this JavaScript tutorial and learn about two useful JSON methods that are used for converting JavaScript object into string and vice versa easily.
The JSON object has two methods to deal with JSON-formatted content: <kbd class="highlighted">parse()</kbd> and <kbd class="highlighted">stringify()</kbd>. Let’s see what each of them does and what the major differences are between these two methods.
JSON.parse()
The JSON.parse() method takes a JSON string and transforms it into a JavaScript object. Parsing means to divide into grammatical parts and identify the parts and their relations to each other. After parsing the string from web server, it becomes a JavaScript object and then you can access the data. Here is an example of <kbd class="highlighted">JSON.parse()</kbd>:

JSON.stringify()
The JSON.stringify() method takes two additional arguments, where the first one is a replacer function and the second one is a String or Number value to use as a <kbd class="highlighted">space</kbd> in the returned string:
Javascript JSON stringify method
As the web server uses strings, the data being send to the server has to be a string. So the <kbd class="highlighted">JSON.stringify()</kbd> method is designed to convert a JavaScript object into a string to send it to the server.
