ES6 - Arrow function with Array prototype find()

Hi Folks,

Today we are going see Arrow function using find() in Javascript.

find() method search the array of objects  and returns the value of the first element in the array that satisfied condition otherwise it will return undefined

Using this find() we should not to loop the entire object and it will give the result very fast compare to traditional looping.

Example:

var empData = [{"name":"Nookala",  "age": 30},
              {"name":"Gunti",  "age": 27},
              {"name":"Teki", "age": 25 },
              {"name":"Yennam", "age": 42 }];


Now are going to search positive scenario

var result = empData.find(o => o.name === "Nookala");

Result will be

If There is no data in object.

NativeScript Angular by Shiva Prasad, an Angular evangelist and Native Script contributor.

Writing cross-platform mobile apps is not as easy as it may seem. On one hand, it can save money to use a JavaScript-based cross-platform mobile framework. But on the other hand, we'd like to be able to give app users the speed and elegance of a native app.

NativeScript is one such cross platform framework which let's us have the best of both worlds. The UI will be converted to truly native mobile UI, on Android and iOS, while still letting us seamlessly access native API using JavaScript / TypeScript. NativeScript provides day 0 access to 100% of the NativeAPI. What's more, you can even do code sharing between your Web and Mobile application.

Join us as we'll uncover more of the awesomeness of NativeScript.

What is Vue.js

Hi,

Today we are going to learn New JavaScript framework as Vue.js.

What is Vue.js?

Vue (pronounced /vjuː/, like view) is a progressive framework for building user interfaces. Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable. The core library is focused on the view layer only, and is easy to pick up and integrate with other libraries or existing projects. On the other hand, Vue is also perfectly capable of powering sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries.

If you’d like to learn more about Vue before diving in, we created a video walking through the core principles and a sample project.

If you are an experienced frontend developer and want to know how Vue compares to other libraries/frameworks, check out the Comparison with Other Frameworks.

Vue.js is an MIT licensed open source project and completely free to use. However, the amount of effort needed to maintain and develop new features.
