Is it possible to use regex variables in react-router's path?

Question

React

Actually there is a working code:

<Route path='/section/:id(\d+)' component={EditSection} />

And its non-working counterparts:

<Route path={'/section/:id(\d+)'} component={EditSection} />

const pathVariable = '/section/:id(\d+)';
<Route path={pathVariable } component={EditSection} />

The path without a regular expression (\d+) works in both cases, with a regular expression it does not work with curly braces
. What is the fundamental difference between passing a parameter through a string and through curly braces? Why does the regex work in one case and not in the other?

Answer 1

As a result, the problem turned out to be that curly braces are escaped, as opposed to writing through quotes. The solution turned out to be as simple as possible, write \\d instead of \d.

Answer 2

Because the regular expression needs to be escaped, you are now passing it as a simple string. Try to navigate by id with regular expression characters, you should have an EditSection component open.
