This opens up a wide range of possibilities, from building high-performance web applications to serverless functions.

Compiling Kotlin code to WebAssembly allows you to run it directly in the browser or any other environment that supports WebAssembly and meets Kotlin requirements.

Starting from this release, you can use Kotlin/Wasm in your multiplatform projects. We think WebAssembly is a promising technology, and we want to find better ways for you to use it and get all of the benefits of Kotlin. The lazyVal is assigned on first access.Kotlin 1.8.20 introduces a new compilation target called WebAssembly. The following code shows a simple use case. Even if you implement the missing function as an extension function, the cached value is of type val. Therefore it can only be used for read-only val during the first assignment. The problem is that lazy does not implement the setValue function. The drawback of using this method is, that a member wrapped by this delegate can not be reassigned. If you´re not sure how to use delegates in Kotlin, you can check out our Delegation tutorial. Kotlin provides a prebuild property delegate that can wrap any object or member variable. An example could be the Activity class of an Android application. Another reason can be that at the point of the parent object creation we just don’t have access to the concrete objects. This can happen for example if it takes a lot of time to create the object and it makes sense to postpone it to the actual time point when it is used. In some cases, however, it is advantageous to postpone the creation to a later point. In most cases, member variables are initialized when their parent object is created. The lazy initialization pattern, also called deferred initialization, is used to postpone the creation of an object to a later time point. Nullable object What is the lazy pattern?
