Strict Merge
------------
Deep merge two objects with strict type checking.
```javascript
import { strictMerge } from 'strict-merge';
let first = {
foo: {
bar: {
baz: 1,
biz: 2
}
}
}
let second = {
foo: {
bar: {
bas: 3
}
}
}
let result = strictMerge(first, second);
/*
{
foo: {
bar: {
baz: 3,
biz: 2
}
}
}
*/
```
Or provide a merger function to resolve conflicts:
```javascript
import { strictMerge, TYPE } from 'strict-merge';
let first = {
foo: {
bar: {
baz: 1,
biz: 2
}
}
}
let second = {
foo: {
bar: {
bas: 3
}
}
}
let result = strictMerge(first, second, (a, b, type) => {
if (type === TYPE.NUMBER) {
return Math.min(a, b);
}
return b;
});
/*
{
foo: {
bar: {
baz: 1,
biz: 2
}
}
}
*/
```
### Notes:
- Leaf nodes from second argument will take precedence
- Any conflicts between types for leaf nodes will result in an error (e.g. if you try to merge a string with an int)
