Features of global pattern in JavaScript regular expressions

Returns the Boolean value indicating the status of the global flag (g) used by the regular expression. The default value is false. Read-only. Required rgExp parameter is a regular expression object. If the regular expression has a global flag set, the global property returns true, otherwise false. Using the global flag indicates that searching in the string being looked up will look for all matching items, not just the first one. This is also known as global matching.

I have never been very clear about what aspects of javascript's global manifestation, so I specially conducted a few tests today:

var str = 'bbaaabb',
reg = /^b|b$/;
while((str)){
str = (reg,'');
( + ":" + str);
} 

Final result:

//0:baaabb
//0:aaabb
//0:aaab
//0:aaa 

But if you make some modifications

var str = 'bbaaabb',
reg = /^b|b$/g;
while((str)){
str = (reg,'');
( + ":" + str);
} 

The final result is:

//0:baaab
//0:aaa 

This result shows that in global mode, after matching the beginning b character, the ending b character will continue to be matched, thus ignoring the middle "|" operator.

I will introduce so much to you about the global pattern characteristics in JavaScript regular expressions. I hope it will be helpful to you!
