negate(predicate: function): function

Creates a function that negates the result of the predicate `func`. The `func` predicate is invoked with the `this` binding and arguments of the created function.

Example(s):

function isEven(n) {
  return n % 2 == 0
}

filter([1, 2, 3, 4, 5, 6], negate(isEven))
// => [1, 3, 5]

Params:

Name Type Attribute Description
predicate The predicate to negate.

Returns:
