JavaScript How to write a regular expression in no particular order? write regular expression in python,write regular expression online,write

I have to do a javascript check on a string. The string must have 6 letters and 2 numbers but not necessarily in that order, also 2 numbers and 6 letters.

At the time i have:

``````/^[A-Za-z]{6,}[0-9]{2,}\$/;
``````

Thanks a lot!

``````^(?=(.*[0-9]){2})(?=(.*[A-Za-z]){6})[A-Za-z0-9]{8}\$
``````

Assuming your question is how to check for a mixed set of letters and digits with at least 2 digits and 6 letters, I personally would do it like this :

``````var str = "abc12def";
var digits = str.match(/\d/g).length;
var ok = /^[A-Za-z0-9]{8,}\$/.test(str)
&& digits >=2 && str.length-digits>=6;
``````

Here is the answer what I think, took some time for me to post.

``````/^[a-zA-Z]{6}[\d]{2}|[\d]{2}[a-zA-Z]{6}\$
``````

Cheers!!!
