What does "hack" do?

[PavelDvorak]

hello,
does the "hack" do anything particular? or is just an error?

vscode-quick-select/src/extension.ts

Line 30 in 1c8aaa5

var matches = (content.text + "hack").split(char).reduce((acc, p) => {

AI says:

• The text is concatenated with the string "hack" to handle cases where split might otherwise result in empty positions.
• It uses .split(char) to divide the line's text into substrings and calculates the index of each occurrence of char using .reduce.
• The last added fake position due to "hack" is removed using matches.pop().
