what choco can do

let thresholdForAdult = 20;let user = {
"name": "Tom",
"age": thresholdForAdult + 10
}
let userrole = if (user["age"] >= thresholdForAdult) {
return"ADULT"
} else {
return"CHILD"
}
let showNameIfAdult = fn(user) {
if (userrole == "ADULT") {
puts(user["name"])
}
}

(Off topic) why "choco"?

this lang is named after one of my dogs, and "ちょこ"っと使える(can be used a little in Japanese) sounds like "Choco".
