Built-in types

Browser runtime: loading…

Sapphire built-ins are regular objects: strings, numbers, booleans, lists, maps, ranges, and nil can be passed around and sent messages. Each runnable snippet uses the same WASM engine as the playground.

Core values

Sapphire includes the everyday value types you expect:

Type	Examples
`Int`	`0`, `42`, `-7`
`Float`	`3.14`, `-0.5`
`Bool`	`true`, `false`
`String`	`"hello"`
`List`	`[1, 2, 3]`
`Map`	`{ name: "Ada", score: 95 }`
`Nil`	`nil`

Lists and blocks

Lists support familiar iterators: map, each, reduce, select, any?, all?, and friends. Blocks use |x| parameters.

lists.spr

nums = [1, 2, 3, 4]
squares = nums.map { |n| n * n }
sum = nums.reduce(0) { |acc, n| acc + n }
print "squares: #{squares}"
print "sum: #{sum}"

Maps

Map literals use { key: value }; keys are strings, and maps support the same block style for filtering and iteration.

maps.spr

scores = { ada: 95, matz: 88, grace: 91 }
scores["sandy"] = 84

honors = scores.select { |name, score| score >= 90 }
honors.each { |name, score|
  print "#{name}: #{score}"
}

print "students: #{scores.keys}"
