# General Tips⤶
Just because something works doesn't mean it cant work _faster_⤶
⤶
1. **Use Local Varibles**: local variables are accessed by index instead of hash lookup.⤶
2. **Avoid repeated heap allocations**: Creating tables or [closures](https://en.wikipedia.org/wiki/Closure_(computer_programming)) repeatedly can slow down performance.⤶
3. **Prefer inline expressions over function calls**: For example: `tbl[#tbl + 1] = 0` is faster than <page text="table.insert(tbl, 0)" >table.insert</page>⤶
4. **Multiplication Over Division**: `x * 0.5` is faster than `x / 2`⤶
5. **Squaring over exponentiation**: `x * x` is faster than `x^2`⤶
6. **Factor Expressions**: `x*y + x*z + y*z` can become `x*(y + z) + y*z`⤶
