# Finding year that MMA functions were introduced via programmatic calls in the Wolfram Language [duplicate]

Is there a way to find the year that MMA functions were introduced via programmatic calls in the Wolfram Language? I would like to be able to create and manipulate such a list or dataset.

find the year that MMA functions were introduced via programmatic calls

You can use, as an example

 WolframLanguageData["DSolve", "DateIntroduced"]


So it is a matter of just running the above over all the commands you want.

The above returns a DateObject

See Looping through all functions defined in Mathematica for example of looping over all build-in functions.

• +1 We can also write things like WolframLanguageData[All, {"Name", "DateIntroduced"}]. – WReach Jul 28 '20 at 4:33
• Did not know about the WolframLanguageData function. Thanks to both of you. – PaulCommentary Jul 28 '20 at 5:18
• Whoa, that's such a cool function! Thanks for sharing! – Andrew Brēza Jul 28 '20 at 15:11
