At the beginning of the string matches the first test… Then the test \b matches again, as we’re between o and a comma.… Word boundary \b doesn’t work for non-latin alphabets
The word boundary test \b checks that… But \w means a latin letter a-z (or a digit or an underscore), so the test doesn’t work for other characters
چون var بلوکهای کد را نادیده میگیرد، ما یک متغیر گلوبال test… اگر ما به جای var test از let test استفاده میکردیم، سپس متغیر فقط درون if قابل رویت بود:
Please note: the lookahead is merely a test… =€) is just a test that it should be followed by €.
If we check event.code == 'KeyZ' in our code, then for people with German layout such test will pass… prevents the default action, so nothing appears in the <input> for keys that don’t pass the test
That’s to guarantee that there’s no side way for an evil page to test if a link was visited and hence

If your browser reserves the space for a scrollbar (most browsers for Windows do), then you can test
there are two matches:
…But let’s test
Proxies can’t intercept a strict equality test ===
