How does @babel/types.toBindingIdentifierName work?

Sure! @babel/types.toBindingIdentifierName is a function in the Babel library that converts a variable name to a valid binding identifier name in JavaScript. In JavaScript, variable names can include a wide range of characters, including letters, numbers, and certain special characters such as $ or _. However, there are some restrictions on what characters can be used in a binding identifier name, which is the name used to declare a variable, function, or class. The @babel/types.toBindingIdentifierName function takes a string argument representing a variable name and converts it to a valid binding identifier name. The function applies the following rules: If the input string is not a valid identifier, such as a reserved word or a string literal, the function throws an error. If the input string starts with a number, the function prepends an underscore (_) to the string. If the input string contains characters that are not valid in an identifier, such as a hyphen or a dot, the function replaces those characters with underscores. If the input string is a valid identifier, the function returns the input string unchanged. By converting variable names to valid binding identifier names, @babel/types.toBindingIdentifierName ensures that the code generated by Babel is valid and can be executed in a JavaScript environment.

const { toBindingIdentifierName } = require("@babel/types");

const variableName = "foo-bar.baz";
const bindingIdentifierName = toBindingIdentifierName(variableName);

console.log(bindingIdentifierName);
// Output: "foo_bar_baz"

In this example, we first import toBindingIdentifierName from the @babel/types library. We define a variable variableName that contains a string with characters that are not valid in a binding identifier name. We then call toBindingIdentifierName(variableName) to convert the variable name to a valid binding identifier name. The function replaces the hyphen and dot characters with underscores, and returns the resulting string "foo_bar_baz". We log the resulting binding identifier name to the console using console.log(), which outputs "foo_bar_baz". This name can now be used to declare a variable, function, or class in JavaScript.
