(static) update(dst, src) → {object}
JS implementation of Python's dict.update method.
This updates object dst with the properties in src.
Note: This has been deprecated in v0.1.4 in favor
of the faster Object.assign(target, source).
Parameters:

|---|---|---|
dst |
object
|
The object that will be updated |
src |
object
|
The object whose properties will be added to |
Returns:
- Type:
-
object
The updated dst. This is only returned for chaining.
Example
Update object
// returns {a: 1, b: 2, c: 1, d: 3}
const d1 = {a: 1, b: 2};
const d2 = {c: 1, d: 3};
update(d1, d2) // d1 is now `{a: 1, b: 2, c: 1, d: 3}`
