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

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.
