I have some binary data loaded from a file which includes strings but mixed with binary data and created a DataView of it.

I want to find out which, if any, of an array of strings are present in a specific range of that data, and add those that are to an array.

function findStrings(data, startIdx, endIdx, matchStrings) {
  let returnStrings = [];

  ...

  return returnStrings;
}

The strings may be surrounded by any 8 bit code.

The data might be up to 1 Mb. matchStrings is likely to contain 10-100 strings.

Using a regular expression or searching in multiple passes seems very inefficient, so not sure how to approach it, particularly with need to ignore non-ascii characters.
