The flags accessor property represents the flags of the current regular expression object.
The flags accessor property represents the flags of the current regular expression object.
RegExp.prototype.flags has a string as its value. Flags in the flags property are sorted alphabetically (from left to right, e.g. "dgimsuy"). It actually invokes the other flag accessors (hasIndices, global, etc.) one-by-one and concatenates the results.
All built-in functions read the flags property instead of reading individual flag accessors.
The set accessor of flag is undefined. You cannot change this property directly.
/foo/ig.flags; // "gi" /bar/myu.flags; // "muy"
