usage

example

const {
    inplc,
    imtbl,
    gen_all_matches,
    inplc_continuous,        // remove-fst
    inplc_continuous_all,    // remove-all
    imtbl_continuous,        // remove-fst
    imtbl_continuous_all,    // remove-all
} = require("nv-array-subtracted-remove");

 imtbl : immutable
 inplc : inplace     //inplc sometimes is slightly faster than imtbl, but NOT always
