12$: warn on 'x == y;' statement #1132
Description
The following C++ code has a bug:
for (Used_Variable &used_var : current_scope.variables_used) {
if (used_var.kind == Used_Variable_Kind::use) {
used_var.kind == Used_Variable_Kind::use_in_type;
}
}JavaScript code might have a similar bug. For example:
let x;
x == 42;quick-lint-js should warn about such redundant == (or ===) and suggest = instead.
