884 | #### New `export` strategy |
885 | ||
886 | ```js | |
887 | // Before | |
0eee77cb | 888 | const DynamicThreadPool = require('poolifier/lib/dynamic') |
fa0f5b28 | 889 | // After |
0eee77cb | 890 | const { DynamicThreadPool } = require('poolifier/lib/dynamic') |
fa0f5b28 S |
891 | ``` |
892 | ||
893 | But you should always prefer just using | |
894 | ||
895 | ```js | |
0eee77cb | 896 | const { DynamicThreadPool } = require('poolifier') |
fa0f5b28 S |
897 | ``` |
