It has been about 2 months since I have started using Exercism almost on a daily basis and I love the variety of solutions I get in the community solutions. Each time I see a different solution, I want to take it apart to really understand it deeply. So, what I use is the JS REPL Extension inside VSCode…
Here is a screenshot from the experiment I was doing today as a prep for solving the Transpose exercise which involves a 2D matrix
Since I have not used 2D arrray in JS, I wanted to understand it deeply…
Each time I put a variable alone on a line, the extension prints its contents in green to the right (pretty similar to QuokkaJS which I felt was quite restrictive in its free version).
Here is another thing I have tried - here I wanted to understand the output of each part of the chained statement - appending a line with
//= shows the output of that line

A special shout out to @filbo, who is mentoring 2 of my JS exercises and impressed me with the depth of his understanding - i would be grateful if you can post your process along with the comprehensive example you have created to test for the presence of a non-numeric value in a number string as part of
