Should I use encodeURI or encodeURIComponent for encoding URLs?
....
encodeURI assumes that the input is a complete URI that might have some characters which need encoding in it.
encodeURIComponent will encode everything with special meaning, so you use it for components of URIs such as
var world = "A string with symbols & characters that have special meanin...

How do I detect unsigned integer multiply overflow?
... addcarry_u8 or subborrow_u64). Their signature is a bit obtuse:
unsigned char _addcarry_u32(unsigned char c_in, unsigned int src1, unsigned int src2, unsigned int *sum);

In-Place Radix Sort
...though.
Btw: If you're dealing with DNA strings only: You can compress a char into two bits and pack your data quite a lot. This will cut down the memory requirement by factor four over a naiive representation. Addressing becomes more complex, but the ALU of your CPU has lots of time to spend duri...
