+## verydisco
+
+### Instructions
+
+Create a `verydisco.mjs` script that :
+- takes 1 argument from the command line
+- makes it very disco:
+  - cut this argument in 2 (rounded up),
+  - re-compose a word by concatenating the chunks in the other order
+- display the result in console
+
+If the argument passed is a sentence, each word of the sentence must be very disco.
+
+For example:
+- `discovery` would print `verydisco` (🕺🏼) in console.
+- `Node is awesome` would print `deNo si omeawes` in console.
+
+### Notions
