// e.g. fetch will return below object.
// {
// isValid: boolean,
// value: number
// }[]
const result = await aprx(fetch('https://getarray.com'))
.json()
.filter(result => result.isValid)
.map(result => result.value + 1);
console.log(result) // [{isValid: true, value: ...}, ...]
Property access
const aprx = require('aprx');
const x = await aprx(Promise.resolve({x: 100, y: 100})).x
console.log(x) // 100
Specials
construct
const aprx = require('aprx');
const C = aprx(Promise.resolve(class X {}));
const c = await new C();
assert.ok(c instanceof C); // true
for-of
const aprx = require('aprx');
const values = [1, 2, 3];
const value = aprx(Promise.resolve(values));
let index = 0;
for await (const v of value) {
assert.strictEqual(values[index++], v); // true
}
Object functions
keys
const wrapper = aprx(Promise.resolve({a: 1, b: 2, c: 3}));
const keys = await aprx.keys(wrapper);
console.log(keys) // ['a', 'b', 'c']
values
const wrapper = aprx(Promise.resolve({a: 1, b: 2, c: 3}));
const keys = await aprx.values(wrapper);
console.log(keys) // [1, 2, 3]
entries
const wrapper = aprx(Promise.resolve({a: 1, b: 2, c: 3}));
const keys = await aprx.entries(wrapper);
console.log(keys) // [['a', 1], ['b', 2], ['c', 3]]
assign
const wrapper = aprx(Promise.resolve({a: 1, b: 2, c: 3}));
const assigned = await aprx.assign(wrapper, {d: 4});
console.log(assigned) // {a: 1, b: 2, c: 3, d: 4}
