Steve Gravrock 4ddb07ac2d Drop support for Firefox 102, 115, and 128 (old ESRs)

These browsers have bugs that occasionally cause typed array comparisons
to pass when they should fail, or vice versa:

* for...in loops sometimes omit keys, such that two typed arrays with
  different lengths appear to have the same set of keys.
* Typed arrays sometimes have mulitple undefined keys (which is to say that
  the key itself is undefined). Two typed arrays with identical length and
  contents can compare unequal because of the spurious undefined keys.)

Those problems could be avoided by comparing keys 0...length-1 rather than
the actual set of exposed keys, but that would be a pretty nasty breaking
change for anyone whose code tacks extra properties onto typed arrays. So
far these bugs haven't been seen in anything newer than FF 128. Since the
affected browsers are all past end of life, the most sensible thing is to
just stop testing against them.

A JavaScript Testing Framework

Jasmine is a Behavior Driven Development testing framework for JavaScript. It does not rely on browsers, DOM, or any JavaScript framework. Thus it's suited for websites, Node.js projects, or anywhere that JavaScript can run.

Installation

There are several different ways to install Jasmine, depending on your environment and how you'd like to use it. See the Getting Started page for details.

Usage

See the documentation site, particularly the Your First Suite tutorial for information on writing specs, and the FAQ.

Supported environments

Jasmine tests itself across popular browsers (Safari, Chrome, Firefox, and Microsoft Edge) as well as Node.

Environment	Supported versions
Node	20, 22, 24
Safari	26*
Chrome	Evergreen
Firefox	Evergreen, 140
Edge	Evergreen

For evergreen browsers, each version of Jasmine is tested against the version of the browser that is available to us at the time of release. Other browsers, as well as older & newer versions of some supported browsers, are likely to work. However, Jasmine isn't tested against them and they aren't actively supported.

* Supported on a best-effort basis. Support for these versions may be dropped if it becomes impractical, and bugs affecting only these versions may not be treated as release blockers.

To find out what environments work with a particular Jasmine release, see the release notes.
