Description
The value of global
is a Boolean
and true
if the "g
" flag was used; otherwise, false
. The "g
" flag indicates that the regular expression should be tested against all possible matches in a string. A regular expression defined as both global
("g
") and sticky
("y
") will ignore the global
flag and perform sticky matches.
You cannot change this property directly.

Using global
var regex = new RegExp('foo', 'g'); console.log(regex.global); // true
