Compile trailing function commas to ES5
function clownPuppiesEverywhere(
param1,
param2,
) { /* ... */ }
clownPuppiesEverywhere(
'foo',
'bar',
);
This is an example from the Proposal.
Let's say you have this function:
function clownPuppiesEverywhere(
param1,
param2
) { /* ... */ }
clownPuppiesEverywhere(
'foo',
'bar'
);
If you want to have a new parameter called param3
, the diff output would be like that:
function clownPuppiesEverywhere(
param1,
- param2
+ param2, // Change this line to add a comma
+ param3 // Add param3
) { /* ... */ }
clownPuppiesEverywhere(
'foo',
- 'bar'
+ 'bar', // Change this line to add a comma
+ 'baz' // Add param3
);
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:
function clownPuppiesEverywhere(
param1,
param2,
) { /* ... */ }
clownPuppiesEverywhere(
'foo',
'bar',
);
Adding a new parameter would only change one line in the function declaration and one line for each usage:
function clownPuppiesEverywhere(
param1,
param2,
+ param3, // Add param3
) { /* ... */ }
clownPuppiesEverywhere(
'foo',
'bar',
+ 'baz', // Add param3
);
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.
