Is `toNumbers` supposed to mutate data?

^{Originally posted by **scpedicini** June 3, 2024} I think I'm doing something wrong with the newer `compromise/three`. `termList`/`out`/etc. works great, but if I use them in conjunction with `toNumbers` the data seems to mutate in place. Trying to do this: ```ts const text_1 = "There are twenty-four apples and 12000 oranges on the table."; const nat = nlp(text_1); const number_of_numerical_values = nat.values().length; // shows a length of two which is what we would expect so far so good const termList_1 = nat.values(0).toNumber().termList(); console.log(termList_1); // termList_1 has converted the number "twenty-four" to "24" but also has // `"apples", "and", "12000", "oranges", "on", "the", "table"` in array // rerun exact same command const termList_2 = nat.values(0).toNumber().termList(); console.log(termList_2); // termList_2 now has the expected array of just "3" // converted to numerical ``` I basically want to go through each numerically recognized "group" hence using the `.values()` command and use the `toNumbers()` command to reduce them down to the numerical number. Picture to help indicate the issue:

@spencermountain Thanks for taking a look. Just wanted to add some information around this as well - near as I can tell it happens pretty consistently with out, json, termList, etc.

const nat = nlp('There were 24 apples and 12000 oranges on the table.');
