Discover the functional programming interface that makes serverless computations elegant and powerful. This documentation serves as your complete guide to functional programming in the λii ecosystem.
Execute your first lambda function in under 30 seconds:
/**
* @param {string} input
* @return {string}
*/
const identity = λ(input) => input
// Execute in browser
λii.execute('identity', 'Hello, λii')Compose functions like mathematical expressions using λ-calculus principles. Immutable operations ensure side-effect-free computations.
const compose = λ(f, g) => λ(x) => f(g(x))
const add1 = λ(x) => x + 1
const multiply = λ(x) => λ(y) => x * y
// Compose operations
const squarePlusOne = compose(add1, multiply)Automatic type validation for all functions based on Hindley-Milner type system. Type signatures are inferred at runtime.
/**
* @param {number} a
* @param {number} b
* @return {number}
*/
const divide = λ(a) => λ(b) => a / b
// Type system ensures
λii.validate(divide(10)(2)) // Valid
λii.validate(divide(10)("2")) // Type Error
