async/await pattern to ensure seamless, non-blocking
progress while maintaining well-formed HTML output. This research marks a
significant step forward in simplifying server-side rendering workflows for
modern web applications.

Paulo Pereira delivered a presentation titled Kotlin Meetup Lisbon - Mutability: Necessity or Habit. Kotlin, a language designed to emphasize immutability alongside mutability, requires programmers to decide at the point of declaration: variable or value? This approach contrasts with languages like Java, which default to variables and inherently presume the use of mutations. During the presentation, Paulo examined the relevance of mutability in modern software development, questioning whether it is a practical necessity or simply a habit ingrained in the mindset of imperative programmers. He also discussed the implications of choosing immutable data by default and the potential gains or losses from challenging the reliance on mutations.
The session explored these questions from a historical perspective and used simple, practical examples to highlight the merits and trade-offs of immutability as a fundamental design principle in software development.

There are five different scope functions: let, also, with, apply, and run.
They all receive an object and a code block that will have access to that object.
The with function is the only one that receives the object as a regular parameter.
That leaves us with four remaining functions, which can be neatly organized in a two by two table, according to the two differentiating aspects:
How is the object made available to the block - via this or via the lambda’s parameter.
What is the scope function’s evaluation result - the received object or the block’s evaluation result.
For instance, apply provides the context object via this and evaluates to the context object.
This means that the following expression’s evaluation
someObject.apply {
someMethod()
}
someMethod on someObject (this is used implicitly).someObject.The table above can be used to select the most appropriate scope function for a given use case. Just answer these two questions and use them to select the table’s column and row, respectively:
this.Finally, in addition to the previous five scope functions, there is also a run overload that doesn’t receive any object and essentially allows a block to be used as an expression.
Alguns dos temas da conversa:
th:each, th:with, v-for,
v-if, v-bind, etc… On the other hand, an internal DSL like React JSX,
KotlinX.html, or HtmlFlow, let you fluently interleave constructs from the host
language (i.e. JavaScript, Kotlin, or Java, respectively) with the use of HTML.
Providing templating features through specific dialects incur the following drawbacks:
This work shows how an internal domain-specific language (DSL) for HTML (such as HtmlFlow, Kotlinx.html, or React JSX) can suppress the aforementioned limitations. To that end, this work uses the Spring Framework and the well-known sample application PetClinic to show how an internal DSL for HTML provides unopinionated web templates with boundless resolving features only ruled by the host programming language (such as Java, Kotlin, or JavaScript).
