![]() ![]() This program computes the number of male and female candidates. Hence, foreach loop is preferred over for loop when working with arrays and collections.Įxample 3: Traversing an array of gender using foreach loop This is because of its simple and expressive syntax. When we look at both programs, the program that uses foreach loop is more readable and easy to understand. Inside the body of loop, the value of ch is printed. Similarly on the last iteration, the last element i.e. On first iteration, the first element i.e. In the above program, the foreach loop iterates over the array, myArray. When we run the both program, the output will be: H Example 2: Printing array using foreach loop using System ![]() The same task can be done using the foreach loop. Here is an example of iterating through an array using the for loop:Įxample 1: Printing array using for loop using System The number of times the foreach loop will execute is equal to the number of elements in the array or collection. On second iteration, the second element is selected and so on. On first iteration, the first item of iterable-item is stored in element. The in keyword selects an item from the iterable-item on each iteration and store it in the variable element. The in keyword used along with foreach loop is used to iterate over the iterable-item. How foreach loop works? Working of C# foreach loop Here iterable-item can be an array or a class of collection. The foreach loop iterates through each item, hence called foreach loop.īefore moving forward with foreach loop, visit: coffee files anywhere:ĬoffeeScript on the top left, compiled JavaScript output on the bottom right.C# provides an easy to use and more readable alternative to for loop, the foreach loop when working with arrays and collections to iterate through the items of arrays/collections. ![]() Latest Version: 2.7.0 # Install locally for a project: The compiled output is readable, pretty-printed, and tends to run as fast or faster than the equivalent handwritten JavaScript. You can use any existing JavaScript library seamlessly from CoffeeScript (and vice-versa). The golden rule of CoffeeScript is: “It’s just JavaScript.” The code compiles one-to-one into the equivalent JS, and there is no interpretation at runtime. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way. Underneath that awkward Java-esque patina, JavaScript has always had a gorgeous heart.
