I started with the same approach, but there is a gotcha in there.
[1,2,3,4].slice(2,6) will return [3,4]. So the length of a new array is only 2. Have no idea how to fix it so I decided to use the inner cycle.

I did it pretty much the same way but slightly different.
I like your chained functions in the evaluation!

functionsolve(s,d,m){letvc=[];for(leti=0;i<s.length;i++){letc=s.slice(i,i+m);// if c the size of m and d equals c's sum then keep itif((c.length===m)&&(d===c.reduce((a,p)=>p+a,0))){vc.push(c);}}returnvc.length;}

Javascript solution (tried to simplify as much as possible):

In your for loop,

`i`

should stop when`i < = l - m`

? Or would your if statement not run if the segment is less than`m`

?
