@babel/plugin-transform-property-literals
Advanced tools
Package description
The @babel/plugin-transform-property-literals package is a Babel plugin that transforms object properties to use literals when they are valid identifiers. This transformation can help improve code readability and potentially optimize execution by leveraging engine optimizations for property access.
Transforming Reserved Word Properties
Transforms reserved word properties into literal properties if they are valid identifiers, ensuring compatibility and potentially improving execution speed.
{"var": "value"} // Before transformation
{"var": "value"} // After transformationTransforming Numeric Properties
Automatically transforms numeric properties into their literal form, enhancing code readability and leveraging engine optimizations.
{"123": "value"} // Before transformation
{123: "value"} // After transformationThis plugin transforms reserved words into a form that can be safely used as property keys. It is similar to @babel/plugin-transform-property-literals but focuses more on reserved words in JavaScript.
Transforms property mutators to use a more compatible syntax. While it deals with properties, its focus is more on the mutation aspect rather than transforming property keys into literals.
