in Concepts / Strings, word "suffix" should be "prefix".

sentence is:

"In Julia, this is implemented as a macro within the Printf module, hence the @ suffix."

referring to @sprintf.

_ /\ _

'nother typo, in the same concept:

"Many have an an equivalent, named with a ! suffix, that modify the input in place."

the redundant "an".
