Sets value to object according to provided path and returns copy
npm install @mzvonar/setinsetIn   
=========
Sets value in object by path and returns copy. Path can be string or array (e.g. ['user', 'profile', 'gender']).
If any part of path doesn't exist it is created. Always returns new copy of object.
npm install @mzvonar/setin
javascript
setIn(context, path, value, push);

context` | Object in which the value will be set |
| `path` | Must be Array or String. See usage |
| `value` | Value to set in path |
| `push` | Whether to push the value to Array. See usage |Usage
`javascript
import setIn from '@mzvonar/setin';
const context = {
user: {
profile: {
gender: 'female'
}
}
};
const newContext = setIn(context, ['user', 'profile', 'gender'], 'male');
`
returns:
javascript
{
user: {
profile: {
gender: 'male'
}
}
}
` `javascript
const newContext = setIn(context, ['user', 'profile', 'address', 'country'], 'slovakia');
`
returns:
javascript
{
user: {
profile: {
gender: 'female',
address: {
country: 'slovakia'
}
}
}
}
` $3
If fourth parameter is `true` and last item in path is `Array` value is pushed to the Arrayexample:
`javascript
const context = {
user: {
name: 'Mike',
nicknames: [
'terminator',
'maverick'
]
}
};
const newContext = setIn(context, ['user', 'nickanmes'], 'vincent vega');
console.log(newContext);
/*
{
user: {
name: 'Mike',
nicknames: [
'terminator',
'maverick',
'vincent vega'
]
}
}
*/
` mutableSetIn
If you need you can import mutableSetIn, which is exactly the same as setIn, but mutates the original context object without creating copy.Tests
