Strawman: partial application operator

# Ben Aston (8 years ago)

I am looking for a champion for a partial application operator strawman.

A terse, native syntax for partial application that does not affect the target of a function will improve code consistency, clarity of intent and legibility.

Assuming arg1 is defined:

Before:

import _ from 'lodash'; 
const o = { 
 foo: _.partial(foo, arg1),
 bar: bar.bind(null, arg1)
};

After:

const o = { 
 foo::arg1,
 bar::arg1
};

I am aware of another idea entitled "this binding syntax" (tc39/proposal-bind-operator), that uses similar operator syntax to this strawman. I have no doubt there is a better syntax for my strawman!

My apologies. I neglected to include this link in my original email.

I'll invite you to check out this particular Google search, as function binding has been discussed many different times on this list.
