is-mergeable-object

What is is-mergeable-object?

The is-mergeable-object npm package is a utility that helps determine if a JavaScript object is mergeable. This is particularly useful when working with deep merge operations, where you need to know if an object can be merged with another.

What are is-mergeable-object's main functionalities?

Check if an object is mergeable

This feature allows you to check if a given object is mergeable. In the code sample, `obj1` is a plain object and is mergeable, while `obj2` is an array and `obj3` is null, both of which are not mergeable.

const isMergeableObject = require('is-mergeable-object');

const obj1 = { a: 1 };
const obj2 = [1, 2, 3];
const obj3 = null;

console.log(isMergeableObject(obj1)); // true
console.log(isMergeableObject(obj2)); // false
console.log(isMergeableObject(obj3)); // false

lodash

Lodash is a popular utility library that provides a wide range of functions for common programming tasks, including deep merging of objects. The `_.merge` function in Lodash can be used to merge objects, and it internally handles the check for mergeable objects.

deepmerge

Deepmerge is a library specifically designed for deep merging of JavaScript objects. It provides more advanced merging capabilities compared to is-mergeable-object, including array merging strategies and custom merge functions.

merge

The merge package is another utility for merging objects. It offers both shallow and deep merge functionalities and can be used as an alternative to is-mergeable-object for merging purposes.

is-mergeable-object

The biggest difficulty deep merge libraries run into is figuring out which properties of an object should be recursively iterated over.

This module contains the algorithm used by deepmerge.

isMergeableObject(null) // => false

isMergeableObject({}) // => true

isMergeableObject(new RegExp('wat')) // => false

isMergeableObject(undefined) // => false

isMergeableObject(new Object()) // => true

isMergeableObject(new Date()) // => false

isMergeableObject(someReactElement) // => false
