JSON.stringify() vs JSON.parse()
JSON.stringify() and JSON.parse() are both JavaScript JSON APIs, and choosing between them is a common point of confusion. This page compares their syntax, parameters, return values, and typical use cases so you can pick the right one. JSON.stringify(): Converts a JavaScript value to a JSON string. Its syntax is JSON.stringify(value, replacer, space). JSON.parse(): Parses a JSON string into a JavaScript value. Its syntax is JSON.parse(text, reviver). Example of JSON.stringify(): JSON.stringify({a:1, b:2}) // "{"a":1,"b":2}". Example of JSON.parse(): JSON.parse("{\"a\":1}") // {a: 1}. Read the full references for JSON.stringify() and JSON.parse() to see edge cases, time complexity, browser support, and the mistakes developers most often make with each. Both belong to the JSON category in the JS Reference documentation, which covers 2 entries in total. Try both in the JavaScript playground to see the behavioral difference live.
