The conclusion from this blog post is that TypeScript provides two ways to iterate over elements in an array or other iterable objects: a `foreach` loop (for.of) and the `()` method, as well as specific methods for maps and sets like `()` and `()`. Use the forEach() method to iterate through the arrayįor other iterable objects such as maps and sets, you can use for.of loop or their specific methods like `()` and `()`. You can also use the `()` method to loop through an array: Iterate through each element in the array using a foreach loop (for.of loop)Ĭonsole.log(fruit) // This will log each fruit value to the console Here’s an example of how to use a `foreach` loop in TypeScript: It allows you to iterate over elements in an array or other iterable objects, like a typed array, string, or map. Programming GuideĪ `foreach` loop in TypeScript is similar to JavaScript’s `for.of` loop. myArray.forEach((value, i, array) > console.log(i, value)) It’s a little more concise than the for loop, which you may prefer in a lot of situations. We’ll look at examples of using the for.of loop and () method, as well as methods specific to other iterable objects such as maps and sets like () and (). With forEach, you provide an iterator function which TypeScript calls for each element in the array, providing it with the index, the element and the whole array as parameters. This blog post will discuss how to use a `foreach` loop in TypeScript.
