Python print vs Javascript console.log()
In Python:
print [1,2], '\n', [3,4]
would print
[1,2]
[3,4]
In Javascript:
console.log([1,2],'\n',[3,4])
prints
[1,2] '\n' [3,4]
What is the equivalent Javascript statement to the above Python print?
Answer
You are sending three arguments to console.log
console.log([1,2],'\n',[3,4])
Because the first argument, [1,2] doesn't contain formatting elements (e.g. %d), each argument is passed through util.inspect(). util.inspect is returning the string representation of '\n' which is not what you want. You want '\n' to be interpreted.
One solution is to concatenate all arguments into one string
> console.log([1,2]+'\n'+[3,4]);
1,2
3,4
Another is to use formatting elements as placeholders, which util.format will substitute with two array's converted values.
> console.log('%s\n%s', [1,2], [3,4]);
1,2
3,4
I assumed node.js here, but the result in Mozilla is identical.
