It seems from the code snippets that DataViews are strongly typed. So what happens when you load data with the wrong type? Does JavaScript have "undefined behavior"?

It's just a blob of bytes. If you write a 32-bit float and then read an int from the same location, you get whatever int those 32 bits form.

That generally tells me that this tool is meant for developers smarter than me to make the appropriate abstractions for me to use. Not for me to consider this a core part of my web app development toolkit. :)

Very much in keeping with the [Extensible Web Manifesto][1].

Developers solving different problems than you. When you run into a problem that needs this tool don't hesitate to use it. Dealing with data structures like this isn't really harder than the usual JS stuff, just different and a learning curve.

And to be clear, unlike in C it's well-defined what those 32-bits are, because it's defined to be an IEEE 754 binary float32.

The data is converted to the target type. If you pass a string to setFloat64, the string will be converted to float64 first.
