Function peek

Runs the given function, while not subscribing the current scope when reading Store.Store values.

Returns

Whatever func() returns.

Example

import {Store, peek, text} from aberdeen

let store = new Store(['a', 'b', 'c'])

mount(document.body, () => {
    // Prevent rerender when store changes
    let msg = peek(() => `Store has ${store.count()} elements, and the first is ${store.get(0)}`))
    text(msg)
})

In the above example store.get(0) could be replaced with store.peek(0) to achieve the same result without peek() wrapping everything. There is no non-subscribing equivalent for count() however.
