Using IndexedDB - Web APIs
transaction. transactions come from the database object, and you have to specify which object stores you want the transaction to span. once you are inside the transaction, you can access the object stores that hold your data and make your requests. next, you need to decide if you're going to make changes to the database or if you just need to read from it. transactions have three available modes: readonly, readwrite, and versionchange. to change the "schema" or structure of the database—which involves creating or deleting object stores or indexes—the transaction must be in versionchange mode. this transaction is opened by calling the idbfactory.open method with a version specified.

rom a scriptable interface. methods and attributes interfaces declare a series of attributes and methods. attributes in idl are akin to javascript properties, in that they are a getter and (optionally) a setter pair. in javascript contexts, attributes are exposed as a regular property access, while native code sees attributes as a get and possibly a set method. attributes can be declared readonly, in which case setting causes an error to be thrown in script contexts and native contexts lack the set method, by using the "readonly" keyword. to native code, on attribute declared 'attribute type foo;' is syntactic sugar for the declaration of two methods 'type getfoo();' and 'void setfoo(in type foo);'. if foo were declared readonly, the latter method would not be present. attributes support...
...however, the presence of the binaryname property allows the user to select another name to use in native code (to avoid conflicts with other functions). for example, the method '[binaryname(foo)] void bar();' becomes 'nsresult foo()' in native code (note that capitalization is still applied). however, the capitalization is not applied when using binaryname with attributes; i.e., [binaryname(foo)] readonly attribute quux bar; becomes getfoo(quux**) in native code. attributes named 'iid' and methods named 'getiid' are forbidden, although this is checked before binaryname conversion. the implicit_jscontext and optional_argc parameters are properties which help native code implementations determine how the call was made from script. if implicit_jscontext is present on a method, then an additional jsc...

Document.timeline - Web APIs
this timeline is a special instance of documenttimeline that is automatically created on page load. this timeline is unique to each document and persists for the lifetime of the document including calls to document.open(). the time values for this timeline are calculated as a fixed offset from the global clock such that the zero time corresponds to the navigationstart moment plus a signed delta known as the origin time. prior to establishing the navigationstart moment, the document timeline is inactive. note: a document timeline that is associated with a non-active document is also considered to be inactive. ...

EffectTiming.delay - Web APIs

XRRigidTransform.matrix - Web APIs
t will not change either the orientation or position of any point, vector, or object to which it's applied. next, the position is placed into the right-hand column, like this, resulting in a translation matrix that will transform a coordinate system by the specified distance in each dimension, with no rotational change. here px, py, and pz are the values of the x, y, and z members of the dompointreadonly position.

Using the progressbar role - Accessibility
