Package description
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.
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"This Babel plugin transforms Unicode text into escaped ASCII form, which can be useful for avoiding encoding issues or for representing non-printable characters in a readable format. It is similar to @babel/plugin-proposal-json-strings in that it deals with string encoding, but it is more general in its approach.
JSON5 is a JS library and npm package that allows for the parsing and serialization of a superset of JSON that includes features from ECMAScript 5. It is similar to @babel/plugin-proposal-json-strings in that it allows for a more flexible JSON format, including unquoted keys, single quotes, and trailing commas.
