I search on the stackoverflow but still didnt’t understand the message https://stackoverflow.com/questions/27916055/whats-the-meaning-of-gi-in-a-regex?noredirect=1&lq=1
Tell us what’s happening:

Your code so far


let quoteSample = "The five boxing wizards jump quickly.";
let alphabetRegexV2 = /\w/gi; // Change this line
let result = quoteSample.match(alphabetRegexV2).length;

What message do you not understand?


#3

the “gi” part…I created this post just for this “gi” part. I’ve read other answer but couldn’t understand much.

g stands for global. It means it will search everything. The i stands for case insenstitive. meaning it will ignore the case in the search and find both capital and non capital letters.

It’s @Tirjasdyn said, but note that the i is unnecessary here: \w finds and word character, upper or lower case.
