I am working on routing my pages to 404 by using regex instead of a string in react-router path prop

What I have is a list of different routes in the following format:

example defintions

route1

const withdrawRuote = 'user/:userId/withdraw'

const depositRoute = 'user/:userId/deposit'

route2

const groupNewRoute = 'group/new'

const groupWithdrawRoute = 'group/withdraw'

const groupDepositRoute = 'group/deposit'

react-router route path regex

For Route1

Route(exact path=myRegex1 render=404)

here is myRegex1

With the above regex, the following should PASS:

• /user/123/withdrawaaaaa


• /user/123/depositaaaaaa

should FAIL

• /user/123/withdraw


• /user/123/deposit/


• /user/123/withdraw


• /user/123/deposit/


• /user


• /user/

For Route2

Route(exact path=myRegex2 render=404)

Here is myRegex2.
These should PASS:

• /group/not/found


• /group/not

should FAIL

• /group/


• /group


• /group/deposit


• /group/withdraw

I know I can handle 404s using the switch statement but I need to know why this does not work.

How do I make regex know that i need the words deposit & withdraw or user as a word and not just a set of characters considering I am excluding them rather than include.
