Write a function named every that takes two arguments.
arr (array)
predicate (function)
Return true if the predicate function returns truthy for all elements of arr, otherwise return false. The predicate function is invoked with one argument.
element (anything)
For example:
var result = every([1, 2, 3], function(element) {
return element % 2 === 0;
});
console.log(result); // false
result = every([2, 4, 6], function(element) {
return element % 2 === 0;
});
console.log(result); // true
