How to find Javascript syntax errors -

-

I am writing a javascript section of code and making heavy mistakes in syntax. But the only way to figure out the error on which line is to comment on the section of the code written to it and to reload it in the browser, where to say where I am missing ');' is.

How do you "compile" the JavaScript source to make sure that this syntax is correct so that I can debug it in the browser? "Post-Text" itemprop = "text">

Ctrl + Shift +

J , if you make mistakes by your runtime, of course firebug works better, but this is a quick way.

oracle - The fastest way to check if some records in a database table? -

I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value.

If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
