Deep
Ultra small footprint merge & freeze methods.
deepMerge
This method is like assign
except that it recursively merges own and
inherited enumerable string keyed properties of source objects into the
destination object. Source properties that resolve to undefined
are
skipped if a destination value exists. Array and plain object properties
are merged recursively. Other objects and value types are overridden by
assignment. Source objects are applied from left to right. Subsequent
sources overwrite property assignments of previous sources.
For the most cases it is compatible with lodash.merge package.
deepFreeze
This method executes an recursive Object.freeze.
Installation
Using npm:
$ {sudo -H} npm i -g npm
$ npm i --save @pomgui/deep
In Node.js:
var { deepMerge } = require('@pomgui/deep');
With typescript:
import { deepMerge } from '@pomgui/deep';
Usage
deepMerge
const object = {
'a': [{ 'b': 2 }, { 'd': 4 }]
}
const other = {
'a': [{ 'c': 3 }, { 'e': 5 }]
}
deepMerge(object, other)
// => { 'a': [{ 'b': 2, 'c': 3 }, { 'd': 4, 'e': 5 }] }
### deepFreeze
const frozen = deepFreeze(obj);
// frozen === obj
const frozenArr = deepFreeze(obj1, obj2, obj3);
// frozenArr[0] === obj1
// frozenArr[1] === obj2
// frozenArr[2] === obj3
