Question

Suandi is documenting the technology choices of his Web development team. In the document, he explains his reasons for using JavaScript as a development language on the client side because:

  • Bit is compatible with the widest variety of Web browsers.
  • Cit is the scripting version of the popular Java programming language.

Explanation

JavaScript is correct as B because it is a web standard supported natively by virtually all modern browsers (Chrome, Firefox, Safari, Edge, etc.) - making cross-browser compatibility its defining practical advantage for client-side development.

Why the distractors are wrong:

  • A is wrong because JavaScript compatibility is not tied to open-source browsers specifically - it works equally in proprietary browsers like older IE or Safari.
  • C is wrong because JavaScript is not a scripting version of Java - they share a superficially similar name for marketing reasons (Java was popular when JavaScript launched in 1995), but they are completely different languages with different syntax, runtime, and purpose.
  • D is wrong because JavaScript was created by Netscape, not Microsoft, and was never exclusive to Internet Explorer - IE actually had its own rival scripting language called VBScript.

Memory tip: Think "JavaScript = Universal Browser Language." The key word in the question is client side - the whole point of running JS in the browser is that users don't need to install anything extra, which only works if all browsers already support it.
