Why is splice() not working in the web editor?

[GoToLoop]

Strange access to data class

Both outputs in my browser got the expected values: [1, 2, 3] & [3, 1, 2]. But b/c you’re printing an array, if a browser by chance delays the actual printing to the console, it’s possible that you’ll see the array’s most current values for all outputs. As a workaround you can extract the arrays values when printing it using the spread ... syntax: console.log(...myTest.groupe);
