len("hello")                // 5
upper("hello")              // "HELLO"
lower("HELLO")              // "hello"
split("a,b,c", ",")         // ["a", "b", "c"]
join(["a", "b", "c"], ",")  // "a,b,c"
trim("  hello  ")           // "hello"
replace("hello", "l", "r")  // "herro"
starts_with("hello", "he")  // true
ends_with("hello", "lo")    // true

push(arr, 6)        // [1, 2, 3, 4, 5, 6]
pop(arr)            // 6 (removes last)
has(arr, 3)         // true
reverse(arr)        // [5, 4, 3, 2, 1]
sort(arr)           // [1, 2, 3, 4, 5]

type_of("hello")     // "string"
type_of([1, 2, 3])   // "array"

clock()              // Current timestamp
sleep(1000)          // Sleep 1 second (ms)

assert(1 == 1)       // No-op
assert(1 == 2)       // Runtime error
