How do I sort one vector based on the values of another?

Say I have predefined order:

(def order ["0M","6M","1Y","2Y","3Y"])

I have another vector ["0M","1Y","6M"] (may or may not contain all elements of vector “order”)

Output should be ["0M","6M","1Y"]

    (def order ["0M","6M","1Y","2Y","3Y"])
    
    (sort-by #(.indexOf order %) ["0M", "1Y", "6M"]) ; ("0M" "6M" "1Y")
    

    Notice that sort-by returns a sequence. If you absolutely need a vector result, you can feed the output to vec.
