methods
var merge = require('deepmerge')
merge(x, y, opts)
Merge two objects x
and y
deeply, returning a new merged object with the
elements from both x
and y
.
If an element at the same key is present for both x
and y
, the value from
y
will appear in the result.
The merge is immutable, so neither x
nor y
will be modified.
The merge will also merge arrays and array values.
options
arrays
merge
(default) - Replace array values at index. e.g.[1, 2] + [3] => [3, 2]
concat
- Push value to the bottom of the array. e.g.[1, 2] + [3] => [1, 2, 3]
