简介
The (archimedean) spiral is formed by a lambda expression shown below. It performs computation similar to [1, 2, 3].map(elem => elem - 1) (JavaScript).(f => (x => f(n => x(x)(n)))(x => f(n => x(x)(n))))(m => l => f => (_ => _)((l => l(_ => _ => (_ => f => f(_ => _))))(l))(_ => (_ => (f => _ => f(_ => _))))(_ => (h => t => (l => r => f => f(l)(r))(h)(t))(f((p => p(l => _ => l))(l)))(m((p => p(_ => r => r))(l))(f))))((e => (l => (f => (x => f(n => x(x)(n)))(x => f(n => x(x)(n))))(v => r => l => (_ => _)((l => l(_ => _ => (_ => f => f(_ => _))))(l))(_ => r)(_ => v((h => t => (l => r => f => f(l)(r))(h)(t))((p => p(l => _ => l))(l))(r))((p => p(_ => r => r))(l))))(_ => (f => _ => f(_ => _)))(l))(e(_ => _ => (f => _ => f(_ => _)))))((f => (x => f(n => x(x)(n)))(x => f(n => x(x)(n))))(r => t => h => (_ => _)((n => n(_ => (_ => f => f(_ => _)))(_ => f => f(_ => _)))(h))(_ => t)(_ => r((h => t => (l => r => f => f(l)(r))(h)(t))(h)(t))))(_ => (f => _ => f(_ => _)))(f => x => f(x))(f => x => f(f(x)))(f => x => f(f(f(x))))))(e => (m => n => n(n => (p => p(l => _ => l))(n(p => (l => r => f => f(l)(r))((p => p(_ => r => r))(p))((n => f => x => f(n(f)(x)))((p => p(_ => r => r))(p))))((l => r => f => f(l)(r))(_ => _)(_ => x => x))))(m))(e)(f => x => f(x))) The expression is also a legal ES6 arrow function. You can save the following code to a .js and use Node.js to run it. let lt = (f => (x => f(n => x(x)(n)))(x => f(n => x(x)(n))))(m => l => f => (_ => _)((l => l(_ => _ => (_ => f => f(_…
