Repeat a string with a delimiter

Assuming a string

A = 'abc';

How to repeat it for several times, say 3 times, with a delimiter ',', so that to obtain:

'abc, abc, abc'

Is there a neat solution to do so?

A = 'abc';
B = join(repmat({A},1,3),', ');
B = B{1}

B = 'abc, abc, abc'

C = join(repmat(string(A),1,3),', ') % string output!

C = "abc, abc, abc"

D = sprintf('%1$s, %1$s, %1$s',A)

D = 'abc, abc, abc'
