Why you should care

[/vc_column_text][vc_column_text]Using return, break, throw, and continue from a finally block overwrites similar statements from the suspended try and catch blocks.[/vc_column_text][vc_empty_space][/vc_column_inner][/vc_row_inner][vc_empty_space height=”12px”][vc_empty_space][vc_separator][vc_column_text]

How we detect

[/vc_column_text][vc_column_text]CAST Highlight counts one occurrence each time a jump statement (break, continue, return and throw) would force control flow to leave a finally block.

Bad Code

try {
console.log('test')
}
catch(e) {
console.log(e);
}
finally{
throw new Error('Something bad happened'); // Noncompliant
}

Good Code

function foo() {
try {
return 1; // We expect 1 to be returned
} catch(err) {
return 2; // Or 2 in cases of error
}
}
