How do I create a JSON string in JavaScript?

To create a JSON string in JavaScript, you can use the JSON.stringify(value, replacer, space) method. The JSON.stringify() method serializes (converts to string) objects, arrays, or primitive values ​​into a JSON string. The JSON.stringify() method takes three parameters. The first parameter is the object to be converted to a JSON string. The second optional parameter is a function that changes the behavior of the serialization process; if the value is blank or null, then all properties of the object are included in the string. The third optional parameter is an argument used to control the spacing in the final string; if this parameter is not specified then its value is "null". In this JavaScript JSON Stringify Example, we use the JSON.stringify() method to convert an object to a JSON string.
