ASCII character codes between 0 and 32 are reserved for non-printing characters. Such characters are unlikely to be present in JavaScript strings, and matching them with a Regular expression is most likely a mistake. Even when you do want to match them, it is recommended to use the character literals for better clarity:
const tabsAndSpaces = / \t/
const tabsSpacesAndNewLines = /\s/
If you find yourself needing to match the hex values for some reason, consider adding a skipcq comment to inform readers about the use-case. This will also prevent DeepSource from raising the issue.
const rSpaces = /\x1a/;
// A regex like this one is rarely useful:
const regExp = new RegExp("\x12");
const rSpaces = / /;
const regExp = new RegExp("[\sa-z]+no-control-chars-here");
