es-abstract's Introduction

es-abstract

ECMAScript spec abstract operations.

Every operation is available by edition/year and by name - for example, es-abstract/2020/Call gives you the Call operation from ES2020, es-abstract/5/Type gives you the Type operation from ES5.

All abstract operations are also available under an es5/es2015/es2016/es2017/es2018/es2019/es2020/es2021 entry point, and as a property on the main export, but using deep imports is highly encouraged for bundle size and performance reasons. Non-deep entry points will be removed in the next semver-major release.

Example

var ES = require('es-abstract');
var assert = require('assert');

assert(ES.isCallable(function () {}));
assert(!ES.isCallable(/a/g));

Tests

Simply clone the repo, npm install, and run npm test

Security

Please email @ljharb or see https://tidelift.com/security if you have a potential security vulnerability to report.

eslint is a devDependency of this project. It might not break your production code or affect downstream projects, but probably breaks your build or test tools, which may prevent deploying or publishing.

ES.isCallable not spec compliant

It looks like ES.isCallable simply leverages the is-callable package. However as noted in inspect-js/is-callable#16, that implementation is not equivalent to the IsCallable from the spec.

Class constructors do have a [[Call]] internal slot which makes them callable.
The [[Call]] internal method throws TypeError if [[FunctionKind]] == "classConstructor", but that's simply the implementation of the internal method.

An in-range update of eslint is breaking the build 🚨

The devDependency eslint was updated from `6.5.1` to `6.6.0`.

Why are spackled scripts copies instead of aliases?

The spackle.js script generates:

'use strict';

module.exports = require('../<prevYear>/<opName>');

But the repository contains copies of the files.

ES‑Abstract v2.0

ES2018 included breaking changes to some abstract operations, most notably #67 and #68.

There’s also #62, which itself is a possible breaking change.

I propose the following breaking changes be made as part of the v2.0 release:

Remove the es6.js and es7.js legacy aliase files for es2015.js and es2016.js.
Apply #67
Apply #68

Test failures with es-to-primitive 1.1.1

Using es-abstract with es-to-primitive 1.1.1 three test failures are reported:

I presume this is related to ljharb/es-to-primitive#2 but I'm unsure if the problem is with that fix, if es-abstract needs to react to that change, or if these tests need fixing...

ToNumber not working with Date objects

https://github.com/ljharb/es-abstract/blob/master/es2015.js#L67

var value = isPrimitive(argument) ? argument : toPrimitive(argument, 'number');

seems that it should be

var value = isPrimitive(argument) ? argument : toPrimitive(argument, Number);

As according to es-to-primitive, the PreferredType should be String or Number if supplied.

Version 10 of node.js has been released

Version 10 of Node.js (code name Dubnium) has been released! 🎊

To see what happens to your code in Node.js 10, Greenkeeper has created a branch with the following changes:

Added the new Node.js version to your .travis.yml
The new Node.js version is in-range for the engines in 1 of your package.json files, so that was left alone

If you’re interested in upgrading this repo to Node.js 10, you can open a PR with these changes. Please note that this issue is just intended as a friendly reminder and the PR as a possible starting point for getting your code running on Node.js 10.

More information on this issue

Greenkeeper has checked the engines key in any package.json file, the .nvmrc file, and the .travis.yml file, if present.

engines was only updated if it defined a single version, not a range.
.nvmrc was updated to Node.js 10
.travis.yml was only changed if there was a root-level node_js that didn’t already include Node.js 10, such as node or lts/*. In this case, the new version was appended to the list. We didn’t touch job or matrix configurations because these tend to be quite specific and complex, and it’s difficult to infer what the intentions were.

For many simpler .travis.yml configurations, this PR should suffice as-is, but depending on what you’re doing it may require additional work or may not be applicable at all. We’re also aware that you may have good reasons to not update to Node.js 10, which is why this was sent as an issue and not a pull request. Feel free to delete it without comment, I’m a humble robot and won’t feel rejected 🤖

Reduce the size of the npm package by limiting the included files

Looks like the files property (https://docs.npmjs.com/files/package.json#files) is not used in package.json to specify the included files, nor is the .npmignore file (https://docs.npmjs.com/misc/developers#keeping-files-out-of-your-package) is being used for blacklisting unwanted files, for the package published to npm.

Would you consider adding either the files property or the .npmignore file, so that the resulting package file would have smaller size?

The current size can be seen when executing the command npm pack (https://docs.npmjs.com/cli/pack).

[email protected] release breaking old applications

I am currently experiencing an issue where which was already raised by another person on stackoverflow where the latest release [email protected] which is apparently being auto-installed by common libraries (redux-form, react-date) as a semver range.

Upon building the frontend with webpack and webpack dev server the following error occurs:

Error in ./~/object.entries/implementation.js
Module not found: Can't resolve 'es-abstract/2019/RequireObjectCoercible' in 'someDummyPath/host/client/node_modules/object.entries'

Upon investigating whether the path is really not existing I found out that it is indeed present -> therefore I don't quite understand why this not being resolved properly.

We are using npm modules on a locked version state which stayed the same for a few years - but some of them install dependencies using semver ranges which leads to [email protected] being installed as a peer dependency.

Since we arent the owner of the npm modules we can't simply manually requirea locked version.

Hi.

I developed project with 1.14.0 version, and this is: https://registry.npmjs.org/es-abstract/-/es-abstract-1.14.0.tgz in my package-lock. Today I run npm install and it shows some errors. I checked your .tgz and it says that it is not found. Can you please turn it back?

es-abstract 1.14.0 no longer exists in npm

Hi, 1.14.0 no longer exists on npm as of a couple hours ago which is blowing up whatever version of webpack I'm using. Will hack around it in package-lock.json, but kind of a problem when versions disappear 😄
