[Mark Sir Link]

if you have an array called this.arr, this.arr.name will return arr.

However, I can't see any useful implementation of what you're asking for since searching through the arrays to see what begins with "ingraal" requires you already knowing exactly where they are and searching each one manually.

If you were to pass an array of arrays to the function and check through all the arrays in there, this.collectedarrays[0].name returns nothing.
