Example
Basic
This is an example from the Proposal.
Let's say you have this function:
If you want to have a new parameter called param3, the diff output would be like that:
In total, you have to change 2 lines for the function declaration and 2 lines for each usage.
If you had your function defined with trailing commas:
Adding a new parameter would only change one line in the function declaration and one line for each usage:
In the end, your diff output will be cleaner and easier to read, it would be much quicker to add a new parameter to your functions, it also makes it easier to copy paste elements and move code around.
