 ``++std::format++``, introduced by {cpp}20, enables straightforward string construction out of values of various types.
 
 
-Before {cpp}20 one popular way to obtain the same result was the conversion of the values with ``++std::to_string++`` and piecewise string concatenation.

 ``++std::format++`` is strictly superior. It is more efficient because it constructs the string in-place instead of copying substrings one by one. It is also often shorter and easier to read because the format pattern is presented in a single piece and not scattered across the concatenation expression.
