- mneary 13y agoA far cleaner solution: console.log(process.argv.slice(2).reduce(function(a, x) { return a + parseFloat(x) }, 0));
- jamescarl 13y agoAwesome! Thanks a ton for the suggestion.
- dsego 13y agoWhy is that cleaner? A for-loop is one of the basic programming constructs.
- agumonkey 13y agoreduce is one very fundamental construct too https://www.google.com/search?q=universality+of+reduce https://www.google.com/search?q=universality+of+reduce
- mneary 13y agoA for-loop might be a basic programming construct, but it shouldn't be. Mutation and a control flow construct makes for a much worse outlook to the problem than does recursive application of a function.
- Scryptonite 13y agoLeast bytes? var a=process.argv,i=a.length,x=0;while(i>2)x-=-a[--i];console.log(x)
- jamescarl 13y agoThat's a neat approach! Thanks
