length in 2 dimension array

var example is a 2-dimension array. example.length will give values like 14.3
But how can I get an integer for the length of example in second dimension, like 3 in this case?
Thank you!

If the array is homogeneous (which is always the case when such an array is the result of a getValues() call in a spreadsheet range for example) you can simply write :

example[0].length

EDIT : a few comments to be more clear ...

The 2D array you get from example = range.getValues() is always an array of rows data.

The number of rows is represented by example.length and the inner array length (representing rows content) is always example[0].length, which is actually the number of columns
