Partial Application and Lambda Parameter Syntax for JavaScript

You can not use partial application with that. for example const add = x=>y=>x+y

can be partialy applied like the following const add3 = add(3) // this is also a function

You can:

    const add3 = add.bind(null, 3)

I still like currying better, but I just might be weird like that :-)

I only asserted that you could partially apply regular functions. But I don't think currying looks or feels nice in Javascript.

Proper curried languages are definitely better suited for partial application though.

You could use default parameters in this case.

const add = (a, b=0) => {return a+b}
