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 for more information.

•

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.
