Nested if, for, for in, while, do while and switch statements are a
key ingredient for making what’s known as "Spaghetti code".
Such code is hard to read, refactor and therefore maintain.
Noncompliant Code Example
With the default threshold of 3:
if condition1 { // Compliant - depth = 1
/* ... */
if condition2 { // Compliant - depth = 2
/* ... */
for var i = 0; i < 10; i++ { // Compliant - depth = 3, not exceeding the limit
/* ... */
if condition4 { // Non-Compliant - depth = 4
if condition5 { // Depth = 5, exceeding the limit, but issues are only reported on depth = 4
/* ... */
}
}
}
}
}
