I sometimes need to switch to few programming languages that I feel not proficient, But at times should do something with that like execute as a script, evaluate interview, manage/refer others code, find the treasure hidden in large code-base. For example, groovy, python, pl/sql, c# or typescript.
Do you have any tested technique to quickly recollect the entire language? hope few others would be in my situation!
Do you have any technique to come up to speed?
