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 Go.

Javascript Array every in Go With Example Code
JavaScript’s `every()` method is a useful tool for checking if all elements in an array pass a certain test. But what if you’re working in Go and need to replicate this functionality? Fortunately, Go provides a way to achieve this using the `range` keyword and a `for` loop.
To use `every()` in Go, you can create a function that takes in an array and a test function as arguments. The test function should take in an element from the array and return a boolean value. The `every()` function will then iterate over the array using a `for` loop and the `range` keyword, calling the test function on each element. If any element fails the test, the function will return `false`. If all elements pass the test, the function will return `true`.
Here’s an example implementation of `every()` in Go:
func every(arr []int, test func(int) bool) bool {
for _, element := range arr {
if !test(element) {
return false
}
}
return true
}
In this example, the `every()` function takes in an array of integers and a test function that takes in an integer and returns a boolean value. The function then iterates over the array using the `range` keyword and calls the test function on each element. If any element fails the test (i.e. the test function returns `false`), the function returns `false`. If all elements pass the test, the function returns `true`.
To use this function, you can define a test function and pass it to the `every()` function along with an array of integers:
func isEven(n int) bool {
return n%2 == 0
}
func main() {
arr := []int{2, 4, 6, 8, 10}
result := every(arr, isEven)
fmt.Println(result) // Output: true
}
In this example, the `isEven()` function takes in an integer and returns `true` if it’s even and `false` if it’s odd. The `every()` function is then called with an array of even integers and the `isEven()` function as the test function. Since all elements in the array are even, the `every()` function returns `true`.
With this implementation of `every()` in Go, you can easily replicate the functionality of JavaScript’s `every()` method and check if all elements in an array pass a certain test.
Equivalent of Javascript Array every in Go
In conclusion, the equivalent Javascript Array every function in Go provides a powerful tool for developers to filter and manipulate arrays in their Go programs. By using the every function, developers can easily check if all elements in an array meet a certain condition, and perform further actions based on the result. While the syntax and implementation may differ from Javascript, the concept remains the same and can be easily adapted by developers familiar with both languages. Overall, the every function is a valuable addition to the Go language and can greatly enhance the functionality of array manipulation in Go programs.
