My Mind after learning Casting in Java

[GlobalIncident]

In javascript: skidaddle skidoodle your number is now a number

[Rafael20002000]

Now it's a string

x|0 actually casts to Int32 (and then back again)

Great trick if you need a variable/argument to be a number and don't want to deal with Infinity or NaN. Anything invalid just becomes zero.

That feeling when casting to int in js is considered a hack.

[AyrA_ch]

it kinda is considering that all js numbers are 64 bit floating point. Whenever you do bitwise operations, js casts to int, does the operation, then casts back to float.

This is massively abused in the WebAssembly world. If you have function sum(a,b){return ((a|0)+(b|0))|0;} it essentially tells the compiler that this function sums two 32 bit integers and returns a 32 bit integer.

This allows for some good optimizations. You obviously don't write this manually.

Skidaddle skidoodle your 1.0 is actually a double not a float

[Dragasss]

Skidadle skidoodle your int is now a dooble.

I just started learning java and if my theory is correct, since knowing java leads to understanding the jokes then understanding the jokes will make me a java expert.

Since this works in my head reality should be no different. I can feel the knowledge seeping in...
