- They are fixed size, continiguous memory chunks
- That means you cannot grow it
- There is no "insertAt" or push or pop. Doesn't mean you can't write those though
// The memory part, where we define the size const a = new ArrayBuffer(6) // the array view const a8 = new Uint8Array(a) a8 = 45; a8 = 45; // the array view const a16 = new Uint16Array(a); a16 = 0x45454; a16 = 0x45454; console.log(a8) console.log(a16) console.log(a8)
const arr = 
- Because it grows.
Array suck, this is why!
- Deletion: You can't delete, but you can zero it.
- Insertion: You can't insert, but you can write it.
- Its ungrowable: It fixed.
