@babel/helper-simple-access

What is @babel/helper-simple-access?

The @babel/helper-simple-access package is designed to simplify the process of accessing properties on objects in a way that is compatible with the latest ECMAScript standards. It is particularly useful when working with Babel, a JavaScript compiler that allows developers to use next-generation JavaScript, today. This helper package provides functionalities to read and write properties in a manner that ensures the correct execution of getters/setters and adherence to the semantics of the ECMAScript specification.

What are @babel/helper-simple-access's main functionalities?

Simplified Property Access

This feature allows for simplified access to object properties, ensuring that any getters/setters are correctly invoked.

import { simpleAccess } from '@babel/helper-simple-access';

const obj = { a: 1 };
simpleAccess(obj, 'a', true); // Simplified way to access property 'a' of obj

Safe Property Modification

Enables safe modification of object properties, ensuring that the property's setter, if any, is correctly invoked.

import { simpleAccess } from '@babel/helper-simple-access';

let obj = { a: 1 };
simpleAccess(obj, 'a', false, 2); // Safely modifies property 'a' of obj to 2

Other packages similar to @babel/helper-simple-access

@babel/traverse

Similar in the ecosystem of Babel helpers, @babel/traverse allows for navigating through the AST (Abstract Syntax Tree) of a JavaScript program. While it provides more general functionalities for AST manipulation, @babel/helper-simple-access focuses specifically on simplifying property access within the code being transformed.

lodash.get

Lodash's get function is a utility that allows for safe access to object properties, even deep properties. Unlike @babel/helper-simple-access, lodash.get is not specifically designed for use with Babel or the transformation of JavaScript code but is a general-purpose utility for safe property access.

reflect-metadata

This package provides decorators and metadata reflection features for JavaScript. While it operates in a different domain by enabling metadata annotations and reflection, it shares the concept of enhancing language features for more expressive code, similar to how @babel/helper-simple-access enhances property access.

@babel/helper-simple-assignment

There are many cases where it is hard to perform transformations because a piece of code is using complex structures. Say you want to rewrite all accesses to a given variable, and there are cases like

i += 1
--i;

It is difficult to work with.

This helper can handle converting these to simple access patterns of standard assignment. This plugin does not handle

{ a } = foo;

so assignment to patterns still needs to be handled when you are processing updates to values.
