ID: typescript-code-style/no-lonely-if
Language: TypeScript
Severity: Notice
Category: Best Practices
Prefer else if statement instead of an lonely if statement, it is considered cleaner code.
if (a) {;} else { if (b) {;} }
if (a) {
foo();
} else {
if (b) {
bar();
}
}
if (a) {
foo();
} else /* comment */ {
if (b) {
bar();
}
}
if (a) {
foo();
} else {
/* otherwise, do the other thing */ if (b) {
bar();
}
}
if (a) {
foo();
} else {
if /* this comment is ok */ (b) {
bar();
}
}
if (a) {
foo();
} else {
if (b) {
bar();
} /* this comment will prevent this test case from being autofixed. */
}
if (foo) {} else { if (bar) baz(); }
// Not fixed; removing the braces would cause a SyntaxError.
if (foo) {} else { if (bar) baz() } qux();
// This is fixed because there is a semicolon after baz().
if (foo) {} else { if (bar) baz(); } qux();
// Not fixed; removing the braces would change the semantics due to ASI.
if (foo) {
} else {
if (bar) baz()
}
[1, 2, 3].forEach(foo);
// Not fixed; removing the braces would change the semantics due to ASI.
if (foo) {
} else {
if (bar) baz++
}
foo;
// This is fixed because there is a semicolon after baz++
if (foo) {
} else {
if (bar) baz++;
}
foo;
// Not fixed; bar() would be interpreted as a template literal tag
if (a) {
foo();
} else {
if (b) bar()
}
`template literal`;
if (a) {
foo();
} else {
if (b) {
bar();
} else if (c) {
baz();
} else {
qux();
}
}
if (a) {;} else if (b) {;}
if (a) {;} else { if (b) {;} ; }
