For programming, is "add" translated using "agregar" or "añadir"?

Question

Is agregar or añadir (or something else) more correct when describing computer programming actions, for example when adding a string to an array?

arr.append("hola")

Is that:

Agregar la cadena a la matriz

or:

Añadir la cadena a la matriz

What about when describing adding a new function to a class?

Agregue la nueva función a la clase Foo

Final situation: "self must be added as the first parameter"

self debe añadirse como el primer parámetro

Answer 1

As a developer myself, I tend to use añadir more frequently than agregar, mostly because the latter is related to "aggregation" which is also a programming concept and in some contexts might need some disambiguation; although both are generally valid.

If you want to be more specific, you can use concatenar instead when talking about appending to a string.

The only exception would be when talking about arithmetic addition, where one should almost always use sumar.
