@taktikorg/asperiores-beatae

ES Proposal spec-compliant shim for Promise.try. Invoke its "shim" method to shim Promise.try if it is unavailable or noncompliant. Note: a global Promise must already exist: the es6-shim is recommended.

This package implements the es-shim API interface. It works in an ES3-supported environment that has Promise available globally, and complies with the proposed spec.

Most common usage:

1var assert = require('assert');
2var promiseTry = require('@taktikorg/asperiores-beatae');
3
4promiseTry(function (e) {
5	throw e;
6}, 42).catch(function (e) {
7	assert.equal(e, 42);
8});
9
10promiseTry(function () {
11	return Infinity;
12}).then(function (x) {
13	assert.equal(x, Infinity);
14});
15
16promiseTry.shim(); // will be a no-op if not needed
17
18Promise.try(function () {
19	throw 42;
20}).catch(function (e) {
21	assert.equal(e, 42);
22});
23
24Promise.try(function () {
25	return Infinity;
26}).then(function (x) {
27	assert.equal(x, Infinity);
28});
