How to use .every() method in Javascript

The `.every()` method in JavaScript is a built-in array method used to check if every element in an array satisfies a condition specified by a callback function.

It returns a boolean value (`true` or `false`) indicating whether all elements meet the condition.

const numbers = [5, 10, 15, 20, 25];

// Use .every() to check if all elements are greater than zero
const allGreaterThanZero = numbers.every(num => num > 0);

console.log(allGreaterThanZero); // true

In this example, the .every() method is used to check if every element in the numbers array is greater than zero. Since all elements satisfy this condition, the variable allGreaterThanZero will be true.
