Unless you declare the function as private or fileprivate, which limit the visibility to the file or scope where it is defined, you can use it anywhere in the module if declared as internal (the default), and also from external modules if declared as public or open. However since you say that you need it … Read more
You can export multiple functions from a file, no React needed per se: Helpers.js: export function plus(a, b) { return a + b; } export function minus(a, b) { return a – b; } export function multiply(a, b) { return a * b; } export function divide(a, b) { return a / b; } You … Read more
The def declares a method within a surrounding object/class/trait, similar to the way you define methods in Java. You can only use defs within other objects/classes/traits. In the REPL, you cannot see the surrounding object because it’s “hidden”, but it does exist. You cannot assign a def to a value, because the def is not … Read more
You can write a module1 that can measure a given function. The following function returns the runtime of a given function in seconds: defmodule Benchmark do def measure(function) do function |> :timer.tc |> elem(0) |> Kernel./(1_000_000) end end Use it like this: iex> Benchmark.measure(fn -> 123456*654321 end) 9.0e-6 If you want to use that for … Read more
Firstly, application (whitespace) is the highest precedence “operator”. Secondly, in Haskell, there’s really no distinction between operators and functions, other than that operators are infix by default, while functions aren’t. You can convert functions to infix with backticks 2 `f` x and convert operators to prefix with parens: (+) 2 3 So, your question is … Read more
After a few hours of reading and experimenting, here are the things that I found out:- Functions in Swift Functions are self-contained chunks of code that perform a specific task. You give a function a name that identifies what it does, and this name is used to “call” the function to perform its task when … Read more
— UPDATE: You should never actually need to use this function. Sass math is very smart about units, and I have never seen a use-case in which stripping units was a better option than simply using correct math to get what you need. See the Sass issue thread where this has been discussed at length. … Read more
First create a final class with a public static method which does exactly the job you want: package com.example; import java.util.Collection; public final class Functions { private Functions() { // Hide constructor. } public static boolean contains(Collection<Object> collection, Object item) { return collection.contains(item); } } Then define it as a facelet-taglib in /WEB-INF/functions.taglib.xml: <?xml version=”1.0″ … Read more
