To check if a function is already bound in JavaScript, you can use the Function.prototype.bind method and compare the function’s name property. Here’s a simple way to do it:

JavaScript

function isBoundFunction(func) {
  return func.name.startsWith('bound ');
}

// Example usage:
function originalFunction() {}
const boundFunction = originalFunction.bind(null);

console.log(isBoundFunction(originalFunction)); // false
console.log(isBoundFunction(boundFunction));    // true
AI-generated code. Review and use carefully. More info on FAQ.
In this example, the isBoundFunction function checks if the function’s name starts with "bound ", which is a convention used by JavaScript to name bound functions1.

If you have any more questions or need further clarification, feel free to ask!
