The `every()` method checks if all the elements in an array pass a test; the test is passed to the method as a function. The method returns *true* if all the elements pass the test, and *false* if otherwise.

> The function returns *false* immediately after encountering the first element that fails the condition.

# Syntax

The syntax is shown​ below:

function isPositive(element) {
  return element >= 0;
}

let arr = [1, 4, 82, 45, 6]
console.log(arr.every(isPositive)); 

let arr = [11, 12, 13, 14, 15]
console.log(arr.every(element => element > 10)); 

function isCanine(element, index, arr) {
  console.log("Checking if " + arr[index] + " is a canine.")
  return (element == "dog" || element == "doggo")
}

let arr = ["dog", "cat", "doggo"]
console.log(arr.every(isCanine));
