Top Web Development Interview Questions for Freshers

1. State any 5  key responsibilities of Web Developers.
   
   It is generally expected that web developers will be able to perform the following tasks:

• Constructing products entails utilising HTML, CSS, JavaScript, PHP, and other pertinent coding languages.

• Crafting applications involves the design, development, testing, debugging, and deployment within a cross-platform, cross-browser environment.

• Formulating design specifications and patterns is a key aspect of optimising web programs.

• Recognising and rectifying bugs, troubleshooting, and addressing website issues are integral tasks.

• Managing the technical facets of a site, including its cache and performance metrics, ensures efficient functioning and capacity for handling traffic.

2. In your opinion, what skills should a good Web Developer have?Web development experts ought to possess the following essential skills:

• Mastery of Hypertext Markup Language (HTML) and Cascading Style Sheets (CSS)

• Comprehensive understanding of Python, Ruby, and PHP

• Familiarity with Domain-Specific Language (DSL), particularly SQL

• A keen understanding of JavaScript and proficiency in utilising JavaScript libraries like JQuery

• Strong problem-solving capabilities

3. Can you tell the difference between XHTML and HTML?The differences between XHTML and HTML are:

• Lowercase formatting is mandatory for all tags in XHTML.

• Double quotes must be employed for all attributes in XHTML.

• Proper closure of tags is a requisite in XHTML.

• Inline elements are not allowed to encompass block-level elements in XHTML.

4. Describe CORS (Cross-Origin Resource Sharing) and elucidate its significance.CORS, or Cross-Origin Resource Sharing, is a browser mechanism facilitating controlled access to resources across different domains (cross-domain requests). In essence, it permits scripts in a browser client to interact with and retrieve resources from origins other than their own.CORS enhances and extends the Same-Origin Policy (SOP), which limits a website’s capability to access resources beyond its source domain. For instance, if a JavaScript application intends to invoke an API (Application Programming Interface) hosted on a different domain, the SOP would normally block such an action. The introduction of CORS was prompted by the need to address constraints imposed by the same-origin policy.

5. Enumerate the recently added input types, APIs, form components, and elements designed to accommodate media content in HTML5.HTML5 has undergone multiple updates in recent years, and the incorporation of various input types has significantly streamlined its functionality. Some of these input types include:

• Colour: Allows users to pick or designate a colour using the colour picker.

• Date: Permits users to select or specify a date from a dropdown calendar.

• Datetime-local: Facilitates the selection of both local date and time by users.

• Email: Provides a field for users to input an email address.

• Month: Enables users to select or designate a month and year from a dropdown calendar.

• Week: Allows users to choose a week and year from a dropdown calendar.
  

  HTML5 presents the following novel form elements:

  • <datalist>: Designates a list of options for input controls.
  • <keygen>: Generates an encryption key.
  • <output>: Specifies the result or output of an expression.
  • <progress>: Indicates progress towards 100% of the maximum value.
    
  • <meter>: Displays a gauge illustrating a general value within a specified range.

  Several new APIs have been introduced in HTML5, including:

  • History API: Grants programs access to the browser’s history.
  • Page Visibility API: Allows the determination of the current visibility state of a page.
  • Battery Status API: Presents the current battery status of the device.
  • User Timing API: Equips programmers with high-precision timestamps for measuring application performance.
  • Vibration API: Offers access to the device’s vibration functionality.

  HTML5 incorporates five elements that facilitate media integration:

  • <audio>: Employed for embedding audio files within a web page.
  • <video>: Utilized for embedding video files on a web page.
  • <source>: Employed to attach multimedia files encompassing audio, video, and images.
  • <embed>: Utilized for embedding external applications, typically multimedia content like audio or video, into an HTML document.
  • <track>: Specifies text tracks associated with audio and video components.

Describe Webpack.

Webpack generates static assets to represent modules containing dependencies. This free and open-source JavaScript module bundler is primarily designed for JavaScript but can also handle modifications of front-end technologies such as HTML, CSS, and images when the necessary loaders are available. When working with modules that have dependencies, it allows for the implementation of various JavaScript files without concerns about loading order, resulting in more concise code.

Additionally, it extends its utility beyond JavaScript, aiding in converting various other file types into modules and assembling multiple JavaScript modules.

 

6. Explain the distinction between the <span> and <div> tags in HTML5.Div TagIn the construction of a web page, a hypertext document created by a website and presented to a user through a web browser, HTML elements play a crucial role in formatting and providing semantics to different segments of the content. The generic HTML elements <div> and <span> are both employed to delineate distinct sections of a website, serving purposes in both structure and styling. This discussion explores the disparities between the HTML tags for <div> and <span>.Span TagFor the purpose of styling text, the versatile inline element <span> is utilised. It applies styling to a specific part of inline content, occupying space only as much as the text itself without necessitating a new line. These tags find application in brief passages of text, images, links, and various other HTML components that can be seamlessly displayed in line with other content.
