JavaScript for PHP developers
JavaScript for PHP developersStoyan Stefanov This document provides an overview of JavaScript for PHP developers. It compares the syntax and core concepts between the two languages. Some of the key points covered include: variables and data types are similar, functions are objects in JavaScript, JavaScript uses prototypes instead of classes, and functions provide scope. The document also summarizes the built-in global functions and properties, common methods for objects like Array and String, and emphasizes that constructor functions are often not needed in JavaScript.
Java script object model
Java script object modelJames Hsieh JavaScript uses objects to organize data. There are primitive values like numbers and strings, as well as object values like arrays, functions, regular expressions, and dates. Objects are collections of key-value pairs and can be created using object or constructor notation. Arrays are objects that hold multiple values and functions can be used as objects by invoking them with the new keyword. Prototypes allow objects to inherit properties from parent objects and form prototype chains. Frameworks like MooTools use classes and inheritance to organize code into reusable objects.
Javascript
JavascriptAditya Gaur The document discusses JavaScript and some of its key features:
- JavaScript is the programming language of the web browser and was originally developed by Netscape under different names before being standardized.
- JavaScript uses a prototypal object model instead of classes, with objects inheriting directly from other objects via prototypal inheritance chains rather than from classes.
- The "new" keyword is used to create objects but can give the misleading impression of classes; functions can also be used to create objects without "new" by returning the object.
Es.next
Es.nextIgnacio Gil This document discusses new features in ECMAScript (ES) 6 including: enhanced object literals with shorthand property and method definitions; destructuring assignment for arrays and objects; template strings for string interpolation; iterators, generators, and for-of loops; modules with named and default exports; and the module loader API. It provides code examples to demonstrate these new features and compares them to CommonJS and ES5 syntax.
Javascript3
Javascript3mozks 1. The new keyword in JavaScript is used to create an instance of an object and link it to a constructor function. It sets the object's internal [[Prototype]] property to the constructor function's prototype property.
2. The prototype property allows methods and properties to be shared among all instances of objects created with a constructor function. Changes to the prototype property are visible to all object instances.
3. In older versions of Internet Explorer, the __proto__ property serves a similar purpose to the prototype property for sharing properties among objects, but __proto__ has been deprecated and prototype should be used instead.

04 Advanced Javascript
04 Advanced Javascriptcrgwbr The document discusses several key aspects of JavaScript functions including:
1. Functions can be defined in 3 ways - with the function keyword, a function expression, or a function declaration.
2. Closures allow functions to access variables from outer scopes even after the outer function has closed. This allows functions to cache values.
3. Functions are objects that can be passed around and assigned to variables like any other object.
4. Prototypal inheritance is used in JavaScript to inherit properties and methods from one object to another using prototypes.
5. The this keyword is dynamically bound based on the invocation context of a function. Understanding how this works is important for using objects correctly.

Async-ronizing Success at Wix - Patterns for Seamless Microservices - Devoxx ...
Async-ronizing Success at Wix - Patterns for Seamless Microservices - Devoxx ...Natan Silnitsky In a world where speed, resilience, and fault tolerance define success, Wix leverages Kafka to power asynchronous programming across 4,000 microservices. This talk explores four key patterns that boost developer velocity while solving common challenges with scalable, efficient, and reliable solutions:
1. Integration Events: Shift from synchronous calls to pre-fetching to reduce query latency and improve user experience.
2. Task Queue: Offload non-critical tasks like notifications to streamline request flows.
3. Task Scheduler: Enable precise, fault-tolerant delayed or recurring workflows with robust scheduling.
4. Iterator for Long-running Jobs: Process extensive workloads via chunked execution, optimizing scalability and resilience.
For each pattern, we’ll discuss benefits, challenges, and how we mitigate drawbacks to create practical solutions
This session offers actionable insights for developers and architects tackling distributed systems, helping refine microservices and adopting Kafka-driven async excellence.

wAIred_RabobankIgniteSession_12062025.pptxSimonedeGijt In today's world, artificial intelligence (AI) is transforming the way we learn.
This talk will explore how we can use AI tools to enhance our learning experiences, by looking at some (recent) research that has been done on the matter.
But as we embrace these new technologies, we must also ask ourselves:
Are we becoming less capable of thinking for ourselves?
Do these tools make us smarter, or do they risk dulling our critical thinking skills?
This talk will encourage us to think critically about the role of AI in our education. Together, we will discover how to use AI to support our learning journey while still developing our ability to think critically.

Integrating Survey123 and R&H Data Using FME
Integrating Survey123 and R&H Data Using FMESafe Software West Virginia Department of Transportation (WVDOT) actively engages in several field data collection initiatives using Collector and Survey 123. A critical component for effective asset management and enhanced analytical capabilities is the integration of Geographic Information System (GIS) data with Linear Referencing System (LRS) data. Currently, RouteID and Measures are not captured in Survey 123. However, we can bridge this gap through FME Flow automation. When a survey is submitted through Survey 123 for ArcGIS Portal (10.8.1), it triggers FME Flow automation. This process uses a customized workbench that interacts with a modified version of Esri's Geometry to Measure API. The result is a JSON response that includes RouteID and Measures, which are then applied to the feature service record.
