YouTube artificially slows down video load times when using Firefox

Is the use of the "E" notation common in JS? I can see that it (could be) less bytes, obviously more efficient for bigger values... Looking at the script I can see it is minified or whatever we call that these days. I guess my question really is: did someone write "5E3" or did the minifier choose it?

(Sorry this is heading into the weeds, but I'm not really a web developer so maybe someone can tell me!)

Almost certainly the minimizer

I wonder if this actually decreases the byte over wire. 5000 compresses a lot better.... sorry for OT

Interesting question. Has anyone tested this?

Totally possible that the minifier did this, yes.

Because 5E3 is shorter than 5000, just like you can often see !0 to get "true" in minimize code because it saves two characters.

In js I thought 1==true, and 1 is shorter than !0 ??

Never seen the use of exponential notation for numbers in js though (not a surprise, I'm not really a programmer), it seems sensible to me from the point of shifting the domain from ms to seconds.

`1==true` but `1!==true` (`===` and `!==` check for type equality as well and while `!0` is a boolean, `1` is not.

Double-equals behaves differently than triple-equals. Minifiers probably can't swap them safely.

!0 === true, but 1 !== true. I don't recall ever needing the strict comparison, but it seems to tickle the fancy of most js programmers.
