Find the length of an array in Chapel

Question

I deal with multiple languages, so I'm always hunting for how to do

var x = [1,2,3,4];
len(x);     // No, python
x.size;     // No, javascript?
x.size();   // Still no, uh Java?
x.length(); // Grrr
size(x);    // Think that one is C, right?

Which one is it? And how does it change for arrays again? The array page could use an example.

Answer 1

The correct answer is javascript:

var x = [1,2,3,4];
writeln(x.size);

For completeness, here is a summary of the built-in types with size-like fields:

• range.size
• domain.size
• array.size
• tuple.size
• string.length
  • (string.size works as of Chapel 1.17 too)
