Crumb is the latest open source programming language, and after its release, it aroused widespread discussion in the programming section of Reddit .
As the title says, Crumb is a functional programming language, and there are no "keywords", everything is a function (0 keywords, everything is a function.). Other features include providing garbage collection (GC), dynamic typing, having a concise syntax, and a detailed standard library.
sample code
table = (map (range 10) {_ y ->
<- (map (range 10) {item x ->
<- (multiply (add x 1) (add y 1))
})
})
(loop 100 {i ->
i = (add i 1)
(if (is (remainder i 15) 0) {
(print "fizzbuzz\n")
} {
(if (is (remainder i 3) 0) {
(print "fizz\n")
} {
(if (is (remainder i 5) 0) {
(print "buzz\n")
} {
(print i "\n")
})
})
})
})
- Implementing the Fibonacci sequence
// use a simple recursive function to calculate the nth fibonacci number
fibonacci = {n ->
<- (if (is n 0) {<- 0} {
<- (if (is n 1) {<- 1} {
<- (add
(fibonacci (subtract n 1))
(fibonacci (subtract n 2))
)
})
})
}
(until "stop" {state n ->
(print (add n 1) "-" (fibonacci (add n 1)) "\n")
})

The standard library includes: IO, Comparisons, Logical Operators, Arithmetic, etc.
