I am working on a program in node.js which is actually js.
I have a variable :
var query = azure.TableQuery...
looks this line of the code is not executing some times.
my question is :
How can I do a condition like:
if this variable is defined do this.
else do this.
I cannot do in js (query!= null)
I want to see if this variable is defined do some thing. how to do this
if ( typeof query !== 'undefined' && query )
{
//do stuff if query is defined and not null
}
else
{
}
