A simple idiomatic way of upserting and replace

simpleUpsert.js

function upsert(ary, pred, val) {
    if (ary.some(item => pred(val, item))) {
        return ary.map(item => (pred(val, item) ? val : item))
    }
  return ary.concat(val);
}
// greedy replace as it replaces all matches of predicate
const replace = (predicate, value, collection) => {
  return collection.map(item => predicate(item, value) ? value : item)
}
// then
replace(item => item.workOrder.id === action.work.id, action.work, workOrders)
