Jump statements, such as return
, break
and continue
let you change the default flow of program execution,
but jump statements that direct the control flow to the original direction are just a waste of keystrokes.
Noncompliant Code Example
function redundantJump(x) {
if (x == 1) {
console.log("x == 1");
return; // Noncompliant
}
}
Compliant Solution
function redundantJump(x) {
if (x == 1) {
console.log("x == 1");
}
}
Exceptions
break
and return
inside switch
statement are ignored, because they are often used for consistency.
continue
with label is also ignored, because label is usually used for clarity. Also a jump statement being a single statement in a block
is ignored.
