has-symbol-support-x

What is has-symbol-support-x?

The has-symbol-support-x npm package is a utility that checks if the current JavaScript environment has native support for ES6 symbols. This can be useful for ensuring compatibility and feature detection in environments where symbols may not be supported.

What are has-symbol-support-x's main functionalities?

Check for Symbol support

This feature allows you to check if the current environment supports ES6 symbols. The code sample demonstrates how to import the package and log the result, which will be a boolean indicating the presence of symbol support.

const hasSymbolSupport = require('has-symbol-support-x');
console.log(hasSymbolSupport); // true or false

Other packages similar to has-symbol-support-x

has-symbols

The has-symbols package is similar to has-symbol-support-x in that it checks for native support of ES6 symbols in the current environment. It provides a simple boolean result indicating whether symbols are supported. Compared to has-symbol-support-x, it offers the same core functionality but may differ in implementation details and additional features.

is-symbol

The is-symbol package checks if a given value is a symbol. While it does not directly check for environment support of symbols like has-symbol-support-x, it is useful for validating if a specific value is a symbol. This can be complementary to has-symbol-support-x when working with symbols in your code.

ECMAScript compatibility shims for legacy JavaScript engines

`es5-shim.js` monkey-patches a JavaScript context to contain all EcmaScript 5 methods that can be faithfully emulated with a legacy JavaScript engine.

es5-sham.js monkey-patches other ES5 methods as closely as possible. For these methods, as closely as possible to ES5 is not very close. Many of these shams are intended only to allow code to be written to ES5 without causing run-time errors in older engines. In many cases, this means that these shams cause many ES5 methods to silently fail. Decide carefully whether this is what you want. Note: es5-sham.js requires es5-shim.js to be able to work properly.

json3.js monkey-patches the EcmaScript 5 JSON implimentation faithfully.

es6.shim.js provides compatibility shims so that legacy JavaScript engines behave as closely as possible to ECMAScript 6 (Harmony).
