Is it possible to use the for…of syntax for a for loop in observablehq?

In regular JavaScript, one can write a for loop using the for…of syntax. Is this possible with observablehq?

const array1 = [1, 2, 3];

for (const element of array1) {
  console.log(element);
}

>Solution :

Not really. As explained in the tutorials, Observable is not [exactly] JavaScript.

In your case, you need to do two things:

First, there is no const, just make a cell with array1 value:

array1 = [1, 2, 3];

Then for the for loop, in a separate cell, put it between curly braces:

{
    for (const element of array1) {
        console.log(element);
    }
}

That cell, of course, will return undefined:
