Sometimes, we want to clone a function with JavaScript.
In this article, we’ll look at how to clone a function with JavaScript.
How to clone a function with JavaScript?
To clone a function with JavaScript, we can create a new function that calls the original function with the same arguments.
For instance, we write
const oldFunction = (params) => {
// ...
};
const clonedFunction = (...args) => oldFunction(...args);
to create the oldFunction function.
Then we make a clone of that by defining the clonedFunction function that takes an unlimited number of arguments and calls oldFunction with all the arguments.
We use ... in the parameter to get the arguments into the args array.
And then we use ... in the oldFunction to spread the args array entries as arguments.
Conclusion
To clone a function with JavaScript, we can create a new function that calls the original function with the same arguments.
