Function diMapOnce

Combine multiple states to one with further caching within diInit callback

Example

const nums = dis((ns, n) => [...ns, n], [])
const prefix = dic<string>()
const numbers = diMapOnce((prefix, nums) => `${prefix} ${nums}`, prefix, nums)
prefix('Numbers: ')
nums(1)
nums(2)
nums(3)
numbers() // Numbers: 1,2,3
nums(4)
numbers() // Numbers: 1,2,3 - because cached
