make a shallow copy of an object or array
you can copy objects shallowly:
var copy = require('shallow-copy');
var obj = { a: 3, b: 4, c: [5,6] };
var dup = copy(obj);
dup.b *= 111;
dup.c.push(7);
console.log('original: ', obj);
console.log('copy: ', dup);
and you can copy arrays shallowly:
var copy = require('shallow-copy');
var xs = [ 3, 4, 5, { f: 6, g: 7 } ];
var dup = copy(xs);
dup.unshift(1, 2);
dup[5].g += 100;
console.log('original: ', xs);
console.log('copy: ', dup);
var copy = require('shallow-copy')
Return a copy of the enumerable properties of the object obj
without making
copies of nested objects inside of obj
.
If obj
is an array, the result will be an array.
If obj
is an object, the result will be an object.
If obj
is not an object, its value is returned.
With npm do:
npm install shallow-copy
