|
The `Store.set()` method stores the value of `value` in the store under key
|
|
`key`, but only if that key does not already hold a value.
|
|
|
|
## Signature
|
|
|
|
```js
|
|
Store store.set(mixed key, mixed value)
|
|
```
|
|
|
|
:::tip
|
|
This method is chainable as it returns the `Store` object
|

|
|
## Example
|
|
|
|
```js
|
|
const store = new Store()
|
|
store.set('example', 'Hi there')
|
|
store.setIfUnset('example', 'Hi again') // This has no effect
|
|
```
