it is the same situation like
apply() & a!applycomponenst() and the newer a!forEach():
isnull and a!isNullOrEmpty() and so on

load is old .

There is a reason for this box.

no it's not, you can check it in documentation and it's quite helpful

why load()? That's an antique function....

load(
local!myMap: { a!map(rollNumber:1,firstName:"something1"),a!map(rollNumber:2,firstName:"something2")},

displayvalue(ri!rollNumber, local!myMap.rollNumber, local!myMap.firstName, null)
)

As per Stefan's response, displayValue will work but only if your use case is to find a unique value of typeId. If the values of typeId can appear more than once then displayValue will only return the first occurrence. If you want to return ALL occurrences of cText for a given typeId then you'll need to take a different approach:

load(
  local!myData: {{cText:"one",typeId:1},{cText:"two",typeId:1},{cText:"three",typeId:3}},
  fn!index(
    fn!index(local!myData,"cText",null),
    wherecontains(ri!typeId, fn!tointeger(fn!index(local!mydata,"typeId",null))
    )
  )
)

You can use the function displayvalue for it. Goes something like displayvalue(ri!typeId, local!array.typeId, local!array.cText, null)
