Redirect URLs from the old domain that ends with trailing slash to the new domain without trailing slash

Question

I'd like to reduce the redirect chains currently I'm dealing with by directly redirecting the URLs from the old domain that ends with a trailing slash to the new domain without a trailing slash.

My current setup does like this:

olddomain.com/page redirects to newdomain.com/page (this is OK)

However, if the user enters olddomain.com/page/ it first redirects to newdomain.com/page/ and then to newdomain.com/page

What I want is to directly redirect olddomain.com/page/ to newdomain.com/page

My .htaccess:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteCond %{HTTP_HOST} ^olddomain.com [NC,OR]
  RewriteCond %{HTTP_HOST} ^www.olddomain.com
  RewriteRule (.*)$ https://newdomain.com/$1 [R=301,L,NC]
</IfModule>

Thank you!

RewriteRule (.*)$ https://newdomain.com/$1 [R=301,L,NC]

If the source URLs may or may not contain a trailing slash, but always redirect to the URL without a trailing slash then make the trailing slash optional in the RewriteRule pattern, but importantly you need to make the * quantifier non-greedy so it does not consume the trailing slash (since the greedy * quantifier will take priority over the optional token that follows).

For example:

 RewriteRule (.*?)/?$ https://newdomain.com/$1 [R=301,L]

The *? quantifier makes it non-greedy, so it consumes as least as possible.

The NC flag is redundant here since the pattern (.*?)/?$ is effectively case-insensitive anyway.
