Package description
The `set-function-name` npm package allows developers to dynamically change the name of a function at runtime. This can be particularly useful for debugging purposes or when working with higher-order functions where maintaining a clear and meaningful stack trace is important. The package provides a straightforward and easy-to-use API for renaming functions.
Setting a function's name
This feature allows you to set a new name for an existing function. The code sample demonstrates how to use `set-function-name` to change a function's name from 'originalFunction' to 'newFunctionName'.
const setFunctionName = require('set-function-name');
function originalFunction() {}
console.log(originalFunction.name); // 'originalFunction'
const renamedFunction = setFunctionName(originalFunction, 'newFunctionName');
console.log(renamedFunction.name); // 'newFunctionName'The `function-name` package offers functionality to get or set a function's name. Compared to `set-function-name`, it provides a more comprehensive solution by not only allowing the setting of a function's name but also retrieving it. This can be particularly useful in scenarios where you need to manipulate and inspect function names dynamically.
Similar to `set-function-name`, the `rename-function` package allows for the renaming of functions. However, it might offer a different implementation or additional features such as compatibility with more environments or stricter error handling. The choice between `set-function-name` and `rename-function` could come down to specific project requirements or personal preference.
