Solution 1:

In IntelliJ (the Java IDE) or PhpStorm (the PHP IDE) it is called Live Templates.

Go to Settings and start typing "live templates" in the search box. On the right panel you can edit and create such templates.

So in your case, you simply type "con" in the abbreviation text box and "console.log();" in the template box text area below. You may even change, with which action you want to expand the template (Tab is default, space and enter are possible).

The live template thing is much more complex than what I wrote above. You can use variables and some context information. For further reading, I suggest the JetBrains / PhpStorm documentation.
