understand this Regular Expression and make it case-insensitive

Question

here this.pattern is an '@mention' of somebody's username

return new RegExp(`(^|\\s|> ?)@(${ this.pattern }(@(${ this.pattern }))?)`, 'gm');

i need to make this mention to be case-insensitive

Use regex101 or jex im regulex to understand and "reverse engineer" such regexes — Marged, Dec 07 '19 at 20:58

The case insensitive flag i can be set:

return new RegExp(`(^|\\s|> ?)@(${ this.pattern }(@(${ this.pattern }))?)`, 'gmi');

This allows the regex to match without modifying the actual regex.
