JSON.parse(JSON.stringify(x)) Purpose?

stackoverflow.com › questions › 24744474 › json-parsejson-stringifyx-purpose

It's a way of cloning an object, so that you get a complete copy that is unique but has the same properties as the cloned object.

var defaultParams = { a : 'b' };
var params = JSON.parse(JSON.stringify(defaultParams));

console.log( params.a ); // b
console.log( defaultParams.a ); // b
console.log( params === defaultParams ); // false

The above outputs false because even though both objects have the a property, with the value b, there are different objects that are independent of each other (they don't refer to the same reference).

The JSON method will only work with basic properties - no functions or methods.

Why use JSON “parse” and “stringify” methods a bad practice to clone objects in JavaScript (2023 update) | by Petro Zubar | Medium

October 10, 2023 - As you can see, you can just lose data of unsupported types when copying your object in such a way. Moreover, JavaScript won`t even warn you about that, because calling JSON.stringify() with such data types does not throw any error.

BigInt and JSON.stringify/JSON.parse - DEV Community

January 5, 2021 - Interesting post, thanks, and it'd be great to have a common convention for all native constructors that can't be serialized, and these two helpers should already work for most cases (missing recursive parse/stringify for special cases such as Map or Set). const serialize = value => `${ value.constructor.name }(${ (typeof value === 'object' && ( ('length' in value) || ('size' in value)) ) ? `[${[...value].map(v => JSON.stringify(v))}]` : value })`; const unserialize = value => { const i = value.indexOf('('); const args = value.slice(i + 1, -1); const constructor = self[value.slice(0, i)]; switch (constructor.name) { case 'BigInt': return constructor(args); default: return new constructor(JSON.parse(args)); } };

You can break the connection between two arrays.

For example:

const bulkAssignTreeView = JSON.stringify(this.bulkAssignTreeViewData);
this.bulkAssignTreeViewData = JSON.parse(bulkAssignTreeView);

How to Use JSON.stringify() and JSON.parse() in JavaScript | Built In

Summary: JSON.stringify() converts a JavaScript object into a JSON string, and JSON.parse() reverses the process. These methods are often used together to handle JSON data, but they don’t support certain types like undefined, Infinity, NaN, ...

A common use of JSON is to exchange data to/from a web server. When receiving data from a web server, the data is always a string. Parse the data with JSON.parse(), and the data becomes a JavaScript object.

JSON.parse() - JavaScript | MDN

JSON.parse( '{"p": 5}', (key, value) => typeof value === "number" ? value * 2 // return value * 2 for numbers : value, // return everything else unchanged ); // { p: 10 } JSON.parse('{"1": 1, "2": 2, "3": {"4": 4, "5": {"6": 6}}}', (key, value) => { console.log(key); return value; }); // 1 // 2 // 4 // 6 // 5 // 3 // "" In order for a value to properly round-trip (that is, it gets deserialized to the same original object), the serialization process must preserve the type information. For example, you can use the replacer parameter of JSON.stringify() for this purpose:

At the end, the final result is constructed by simply concatenating the output from the initial one-byte stringifier with the output from the two-byte one. This strategy ensures we stay on a highly-optimized path for the common case, while the transition to handling two-byte characters is lightweight and efficient. Any string in JavaScript can contain characters that require escaping when serializing to JSON (e.g.
