kesh { }

 

 

A long, long time from now, in the wake of what will no longer be called JavaScript, might be going to have existed a programming language called kesh.

kesh is a simple high-level programming language. Its syntax is a superset of na.

-- function
greet: ([name, age]: #person) -> {                -- typed function (argument unpacking)
    name: name if age > 12 else 'kid'             -- block-scoped declaration (param masking)
    "Hey, { name }!"                              -- the last evaluated expression is returned
}

joe.speak()                                       --> "Hi, I'm Joe."

greet joe                                         --> "Hey, Joe!"
