1

Backbone.JS Segments

In Backbone.js, a segment is a piece of code that is responsible for a specific function or task. For example, a segment may be responsible for rendering a view, handling user input, or communicating with a server.

2

Backbone.JS Functions

In Backbone.js, functions are blocks of code that perform a specific task. Functions may be defined in models, views, or other parts of the codebase, and can be called from other parts of the code to perform their task.

3

TODO Model

A TODO model is a type of model in Backbone.js that is used to represent a single “todo” item. A TODO model may include properties such as a description, a status (e.g., completed or not completed), and a due date.

4

Backbone.JS Scripts

In Backbone.js, scripts are blocks of code that are executed when the application is run. These scripts may include functions, variables, and other code that is needed to initialize the application and perform tasks.

The test is created by a subject-matter expert

Testlify’s skill tests are designed by experienced SMEs (subject matter experts). We evaluate these experts based on specific metrics such as expertise, capability, and their market reputation. Prior to being published, each skill test is peer-reviewed by other experts and then calibrated based on insights derived from a significant number of test-takers who are well-versed in that skill area. Our inherent feedback systems and built-in algorithms enable our SMEs to refine our tests continually.
