What is es-abstract?

The es-abstract npm package provides utility functions for ECMAScript language abstract operations. These operations are the fundamental building blocks of the ECMAScript specification, which JavaScript and other related languages are based on. The package includes methods for type conversion, manipulation of objects, and working with language semantics as defined in various ECMAScript editions.

What are es-abstract's main functionalities?

Type Conversion

Converts a value to a number as per ECMAScript abstract operation ToNumber.

const ES = require('es-abstract');
const value = '123';
const number = ES.ToNumber(value);

Object Manipulation

Gets an array of the own enumerable property names of an object.

const ES = require('es-abstract');
const obj = { a: 1 };
const keys = ES.EnumerableOwnNames(obj);
