    What do we call it if a function is set up to be called at a later time? - ProProfs

    What do we call it if a function is set up to be called at a later time?

    • Recall

    • Callback

    • Delogging

    • Breakpoint

    Correct Answer
    A. Callback
    Explanation
    A callback is a function that is set up to be called at a later time. It is commonly used in programming to achieve asynchronous behavior, where a function can be executed in response to an event or after a certain task is completed. The callback function is passed as an argument to another function, and when the specified event or task occurs, the callback function is invoked. This allows for flexibility and modularity in programming, as different callback functions can be used depending on the specific requirements of the program.

    All the traits below are known as best practices except - ProProfs

    All the traits below are known as best practices except

    • Typing

    • Testing

    • Performance analysis

    • Debugging skills

    Correct Answer
    A. Typing
    Explanation
    The given answer, "Typing," is the correct answer because it is not considered a best practice. While typing accurately and efficiently is important, it is not typically categorized as a best practice in the context of software development or any technical field. Best practices usually refer to methods or techniques that are proven to be effective and efficient in achieving desired outcomes, such as testing, performance analysis, and debugging skills.

     What is the primary modular unit of execution?  - ProProfs

     What is the primary modular unit of execution? 

    • Logging

    • Breakpointers

    • Function

    • Debugging

    Correct Answer
    A. Function
    Explanation
    A function is the primary modular unit of execution in programming. It is a reusable block of code that performs a specific task. Functions allow for code organization, reusability, and abstraction, making it easier to manage and understand complex programs. They can be called and executed multiple times throughout a program, providing a way to break down tasks into smaller, more manageable pieces of code. Functions can have input parameters and return values, allowing for flexibility and modularity in program design.

    • Internet Explorer 8 and earlier

    • Firefox

    • WebKit

    • Internet Explorer 9

    Correct Answer
    A. Internet Explorer 8 and earlier
    Explanation
    Internet Explorer 8 and earlier do not support the rgba format. This format is used for specifying colors with transparency in CSS. Internet Explorer 9 and other browsers like Firefox and WebKit do support the rgba format, allowing developers to create visually appealing and transparent elements on webpages.

    Good tests exhibit the characteristics below except   - ProProfs

    Good tests exhibit the characteristics below except  

    • Repeatability

    • Simplicity

    • Independence

    • Durability

    Correct Answer
    A. Durability
    Explanation
    Durability is not a characteristic that good tests exhibit. Repeatability means that the test can be executed multiple times and produce the same results. Simplicity means that the test is easy to understand and maintain. Independence means that the test does not rely on other tests or external dependencies. Durability, on the other hand, does not directly relate to the quality of a test.

    Simulating the experience of a real event without having to use the browser’s underlying event support is? - ProProfs

    Simulating the experience of a real event without having to use the browser’s underlying event support is?

    • Custom events

    • Induced events

    • Event handler

    • Loose coupling

    Correct Answer
    A. Custom events
    Explanation
    Custom events are a way to simulate the experience of a real event without relying on the browser's underlying event support. They allow developers to create and trigger their own events, which can be useful in situations where the desired behavior is not natively supported by the browser. Custom events provide flexibility and control over event handling, allowing developers to create more interactive and dynamic web applications.
