typed arrays vs arrays use cases webgl

Question

I am a newbie with typed arrays. I looked at few docs online. But, confused - can someone explain in lamen terms?

When is typed array more useful than Arrays? It seems typed arrays are useful when you want to build visualizations using WebGL. What about in a typical JavaScript web development?

Thanks

Typed arrays are more efficient, because they are limited to contain numbers (in contrast to normal arrays, which can contain elements of any type, even of different types in the same array). Typed arrays are useful when dealing with binary data (including images for visualisation), but are not commonly used elsewhere.
