Everyone is laughing over this. An 11 line function as its own NPM module? I am unsure how I feel. The trend has been to smaller and smaller pieces of functionality. I don’t find this outrageous. Still, the parody is funny:

This is really exciting!!! I was a bit disappointed that the right-pad will be out only in 2017. I am looking forward to that release because there is a high demand for it now.
What kind of load balancing is being used on the back-end? I called leftpad(str, ch, len) with the length I needed and noticed that is not very scalable because it is blocking.
A better approach I would recommend to those using it is to call the API in a for loop. In my tests, it had performance very close to those I see in C or assembly.
I was a bit turned off that the free version can only handle strings up to 1024 in length. I know you need to make some money, but it is big turn off for a lot of my projects.
Edit: I finally signed up for it but still noticed that I am only allowed to use 1024. I called your customer support line and they said I was calling the API from multiple IP addresses and for that I need an enterprise license. Please help me with this issue, it is very crucial at this point as my project is in a complete stop because of this.
jameshart makes it sound so real:
Best practice for performance for large left-pad jobs is to call the service recursively using mapreduce. Remember that left-pad(str,pad,n) is equal to left-pad(left-pad(str,pad,n/2),left-pad(“”,pad,n/2),n). This should run in logarithmic time and is highly parallelizable.
If you don’t like the “” magic string in there you could replace it with a call to left-pad(null, null,0).
