Passing additional parameters in higher-order functions

Answer 1

Here's another version with a primitive curry function:

const samples = ["foo", "bar"];

const exclude = function(item,str) {
  return item !== str;
}

function curry(func){
  return function(var1){
    return function(var2){
      return func(var1,var2); 
    };
  };
}

console.log(curry(exclude)('foo')('bar'));  // true
console.log(samples.filter(curry(exclude)('foo')));  // ["bar"]
