示例1: intoExample
function intoExample () {
var inc = function(n: number) { return n+1; };
var isEven = function(n: number) { return n % 2 == 0; };
var apush = function(arr: number[], x: number) { arr.push(x); return arr; };
var xf = t.comp(t.map(inc),t.filter(isEven));
t.into([], xf, [1,2,3,4]); // [2,4]
}示例2: catExample
function catExample () {
var reverse = function(arr: number[]) {
var arr: number[] = Array.prototype.slice.call(arr, 0);
arr.reverse();
return arr;
};
var xf = t.comp(t.map(reverse), t.cat);
t.into([], xf, [[3,2,1],[6,5,4]]); // [1,2,3,4,5,6]
}示例3: it
it('transduces Map without initial values', () => {
let m1 = Map({a: 1, b: 2, c: 3, d: 4});
let xform = t.comp(
t.filter(([k, v]) => v % 2 === 0),
t.map(([k, v]) => [k, v * 2]),
);
let m2 = t.transduce(xform, Map(), m1);
expect(m1.toObject()).toEqual({a: 1, b: 2, c: 3, d: 4});
expect(m2.toObject()).toEqual({b: 4, d: 8});
});示例4: it
it('transduces Stack with initial values', () => {
const v1 = Stack.of(1, 2, 3);
