The JavaScript Array every() function is used to check if all the elements in an array pass a certain test. It takes in a callback function as an argument, which is executed on each element of the array. If the callback function returns true for all elements, then the every() function returns true. If the callback function returns false for any element, then the every() function returns false. The every() function stops executing the callback function as soon as it encounters the first element for which the callback function returns false. If the array is empty, then the every() function returns true. Keep reading below to learn how to Javascript Array every in Kotlin.

Javascript Array every in Kotlin With Example Code
JavaScript’s `every()` method is a useful tool for checking if all elements in an array pass a certain test. In Kotlin, we can achieve the same functionality using the `all()` method.
The `all()` method is an extension function that can be called on any iterable object, including arrays. It takes a lambda expression as an argument, which is used to test each element in the array. The lambda should return a boolean value indicating whether the element passes the test.
Here’s an example of using the `all()` method to check if all elements in an array are even:
val numbers = arrayOf(2, 4, 6, 8)
val allEven = numbers.all { it % 2 == 0 }
println(allEven) // true
In this example, the lambda expression `{ it % 2 == 0 }` tests each element in the `numbers` array to see if it is even. The `all()` method returns `true` because all elements pass the test.
If any element fails the test, the `all()` method will return `false`. For example:
val numbers = arrayOf(2, 4, 7, 8)
val allEven = numbers.all { it % 2 == 0 }
println(allEven) // false
In this example, the lambda expression tests each element in the `numbers` array to see if it is even. The `all()` method returns `false` because the element `7` fails the test.
Using the `all()` method in Kotlin is a simple and effective way to check if all elements in an array pass a certain test.
Equivalent of Javascript Array every in Kotlin
In conclusion, Kotlin provides a wide range of functions that are equivalent to the JavaScript Array functions. These functions are designed to make it easier for developers to work with arrays in Kotlin, and they offer a lot of flexibility and power. Whether you need to sort, filter, map, or reduce an array, Kotlin has a function that can help you get the job done quickly and efficiently. By using these functions, you can write cleaner, more concise code that is easier to read and maintain. So if you’re a JavaScript developer looking to transition to Kotlin, or if you’re just looking for a more powerful way to work with arrays in Kotlin, be sure to check out these equivalent functions and see how they can help you streamline your code.
