Scripting Numbers, Strings, Arrays, and Lists

Use a faster algorithm. Replacing an O(n^2) algorithm with an O(n) algorithm is faster than anything else. See https://en.wikipedia.org/wiki/Big_O_notation.

Avoid concatenating long strings. 100s of characters is OK; 1,000,000s of characters will be slow if you build the string in 1,000,000s of operations.

Use numeric arrays (matrices, not lists).

Use numeric arrays with operators that operate on the entire array.

Avoid writing loops to manipulate numeric arrays.

Use associative arrays for lookups.
