Deep functions are a Production Risk in JavaScript
[/vc_column_text][vc_column_text pl=”0″ pr=”0″ pt=”0″ pb=”0″]This code insight counts one violation each time an artifact (global function or root code) has a too high depth code. Depth is evaluated throught imbrication of following structures :
if, do, for, while, case,
The depth threshold (max valid depth) is tuned to 5.
Example :
function TooDeepFunction () {
while (toto) { // depth 1
print ‘plouf’;
for (;;) { // depth 2
if (BOOL == 1) { // depth 3
print ‘CAST’;
}
else if (name = ‘JOHN DOE’) { // else :depth 3, if: depth 4
echo ‘CAST’;
switch (INDEX) { // depth 5
case 1 :
if (BOOL >= 1) { // depth 6 ==> VIOLATION!
print ‘example’;
}
default :
return;
}
}
}
}

Business Impacts
Combining multiple lines of code on one line is risky because it makes the code unreadable and less productive in the long run.
