Sorting observable arrays

simpleArrayA is an ordered array of numbers:

Inserting new element

simpleArrayA.push()

Replacing all elements

Switching between different sorting functions

switches between ways of sorting:

• (x,y)=>x.v-y.v (according to values) and
• (x,y)=>x.v*x.v-y.v*y.v (according to absolute values)

Dynamically changing sorting functions

availableDNs=new DB.observable([selectedSorting],{type:'oarray',value:[],sort:()=>sorters[selectedSorting()]})

←(dynamic) sort – is similar to compute; it is a function (with no arguments) returning the sorting function.

A real-life example

Sorting domain names either by name or by price:
