JavaScript double colon (bind operator)

Question

No. The bind operator (spec proposal) comes in two flavours:

• Method extraction

  ::obj.method     ≡ obj.method.bind(obj)
  

• "virtual method" calls

  obj::function    ≡ function.bind(obj)
  obj::function(…) ≡ function.call(obj, …)
  

Neither of them feature partial application. For what you want, you should use an arrow function:

(...args) => this.handleStuff('stuff', ...args) ≡ this.handleStuff.bind(this, 'stuff')
