How to use .every() method in Javascript
By Tan Lee Published on Dec 18, 2024 299
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
