98 JS — An Informative Overview

2. The parseInt Radix Trap (Historical)

Before ES5, parseInt("98") worked fine, but parseInt("98", 8) would return NaN because 8 is invalid in base-8. A famous JavaScript joke: Why did the programmer confuse Halloween and Christmas? Because Oct 31 == Dec 25. With 98, parseInt("98", 10) is safe.

The Art of JavaScript Golf

Code golf challenges often have limits like 140, 100, or 98 characters. For example, the classic "FizzBuzz" in 98 characters:

for(i=0;i++<100;)console.log((i%3?'':'Fizz')+(i%5?'':'Buzz')||i)

That snippet is 75 characters. Let's try a more complex challenge: "Find the sum of all numbers from 1 to 98 that are divisible by 7" in under 98 chars:

[...Array(98)].map((_,i)=>i+1).filter(n=>n%7==0).reduce((a,b)=>a+b)
// That's 63 characters.

If you see a reference to "98 js" on GitHub Gist or Stack Overflow, it is often a personal namespace or a file naming convention (e.g., 98-js-solution.js).

Core API Surface (Conceptual)

Note: names below are illustrative; a real implementation would include small documentation for each function.

  • Selector & DOM helpers

    • 98$(selector, root?) — return single Element (first match) or null.
    • 98$all(selector, root?) — return NodeList/Array of matches.
    • 98$create(tag, props?) — create element with attributes, classes, children.
    • 98$wrap(el, wrapper) — wrap element with wrapper.
    • 98$ready(callback) — DOMContentLoaded helper.

  • DOM manipulation

    • html(el, string?) — get/set innerHTML.
    • text(el, string?) — get/set textContent.
    • attr(el, name, value?) — get/set/remove attribute.
    • css(el, prop, value?) — get/set style properties, and cssBatch for multiple props.
    • addClass / removeClass / toggleClass / hasClass.

  • Event handling

    • on(el, event, handler, options?) — add event listener; supports delegation when event is specified with selector overload.
    • off(el, event, handler?) — remove listener.
    • once(el, event, handler) — add listener removed after first call.
    • emit(el, eventName, detail?) — dispatch CustomEvent.

  • AJAX / fetch sugar

    • 98.fetch(url, opts) — tiny wrapper around fetch returning parsed JSON by default if content-type indicates JSON, with simple timeout option.
    • 98.get / 98.post convenience functions.

  • Utilities

    • debounce(fn, wait, options?)
    • throttle(fn, wait)
    • extend(target, ...sources) — shallow merge.
    • isEmpty(obj)
    • qsParse / qsStringify — querystring helpers.
    • uid(prefix?) — small unique id generator.
    • clamp, lerp — tiny math helpers.

  • Small DOM components (optional)

    • Modal.create(options)
    • Tooltip.attach(el, options) These are intentionally basic, meant as reference implementations developers can copy or modify.

Long-tail keywords to include:

  • "JavaScript in 1998 vs now"
  • "Windows 98 JavaScript simulation"
  • "98 character JS challenge"
  • "parseInt 98 radix"
  • "JavaScript Fibonacci 98"
  • "Retro JS code examples from 1998"

5.2. Educational Resource

98.js serves as an excellent case study for web developers. It demonstrates how to build complex UI systems (like window managers) using standard web technologies. It is often cited in discussions about Single Page Applications (SPAs) that do not rely on frameworks like React or Angular.

Compatibility and Polyfills

  • Base implementation targets evergreen browsers (modern Chrome, Edge, Firefox, Safari).
  • Optional tiny polyfills provided separately for:
    • Element.closest (for very old browsers)
    • fetch / Promise (if supporting IE11-era environments) — but including these defeats the minimal footprint goal; recommend progressive enhancement instead.

Use biome or oxlint instead of ESLint for 10–100x speed.
