Is there a way to remove an item from a vector based on index as of now i am using subvec to split the vector and recreate it again. I am looking for the reverse of assoc for vectors?

It may be faster to get the indexes you want.
(def a [1 2 3 4 5])
(def indexes [0 1 3 4])
(time (dotimes [n 100000] (vec (concat (subvec a 0 2) (subvec a 3 5)))))
"Elapsed time: 69.401787 msecs"
(time (dotimes [n 100000] (mapv #(a %) indexes)))
"Elapsed time: 28.18766 msecs"
