Regular expressions in Javascript with limiting amount of numbers/letters

Time:12-28

I am trying to figure out how to write regular expressions in javascript i need to have a three letter group of either ACF, ABQ, or BXD the character after must be hyphen followed by either 6 or 9 then 5 numbers between 0-9

This is my attempt i'm not sure where I am going wrong?

/ACF|ABQ|BXD-^6|9[0-9]{5}

CodePudding user response:

You can group the first 3 alternations in a non capture group, and you should put the ^ at the start of the pattern.

If you want to match 6 or 9 you can use a character class [69]

The $ at the end denotes the end of the string.

The pattern can be written as:

^(?:ACF|ABQ|BXD)-[69][0-9]{5}$
