How to combine a formula with text in one cell?

Question

My spreadsheet contains data divided into weeks in a year and I would like to combine the following two pieces of information in one cell:

• =ISOWEEKNUM(TODAY())
• Calendar week

'Calendar week' being the name of the whole column is just a text that I would like to maintain and the week number would be a help to see what week it is (either before or after the 'Calendar week').

Answer 1

• shorter:

  =ISOWEEKNUM(TODAY())&"Calendar week"

• or with space perhaps (?):

  =ISOWEEKNUM(TODAY())&" Calendar week"

Answer 2

Well, I found one way to do that. Of course, if there is any simpler/faster/better way, do let me know

=CONCAT(ISOWEEKNUM(TODAY()); "Calendar week")
