Most of the time we are dealing with big java script files. And while debugging we need to locate specific line in script files. I realized that there is no information for this in stackoverflow, and wanted to supply answer here. This is how to go to a specific line in a java script file in Chrome Developer Tools. See the answer below.
While a java script file is open in the sources tab, press CTRL + O type a colon and line number after it :[LineNo] (:575 etc) enter.
If you want to go to specific column on a specific line then use two colons to specify line number and column number at the same time :[LineNo]:[ColumnNo] (:575:50 etc) enter.
