Package description

What is @babel/plugin-proposal-json-strings?

The @babel/plugin-proposal-json-strings package is a plugin for Babel that allows you to use the JSON strings proposal in your JavaScript code. This proposal makes it possible to write escape sequences for line separators (\u2028) and paragraph separators (\u2029) within string literals, which are otherwise not allowed in JSON. This can be useful when dealing with JSON data that may include these characters.

What are @babel/plugin-proposal-json-strings's main functionalities?

JSON Strings Proposal Support

This feature allows you to include line and paragraph separators in your JSON strings, which are part of the ECMAScript 2019 (ES10) specification. The plugin transforms these literals into valid JavaScript strings.

"This is a JSON string with a line separator: \u2028 and a paragraph separator: \u2029"
