[−][src]Struct rslint_core::groups::errors::NoConstantCondition
Disallow constant conditions which always yield one result.
Constant conditions such as if (true) {}
are almost always a mistake. Constant
conditions always yield a single result which almost always ends up in unwanted behavior.
This rule is aimed at catching those conditions in if
, do while
, while
, and for
statements, as well as
conditional expressions.
Incorrect Code Examples
if (true) {
// ^ this block is always used
} else {
//^^^^ this else block is unreachable
}
// This loop endlessly runs
for(foo = 5; 5; foo++) {
}
Correct Code Examples
if (foo) {
/* */
}
