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.
