Struct rslint_core::groups::errors::NoDupeKeys [−][src]
pub struct NoDupeKeys {}
Expand description
Disallow duplicate keys in object literals.
Object literals allow keys to be declared multiple times, however this causes unwanted behavior by shadowing the first declaration.
Invalid Code Examples
let foo = {
bar: 1,
baz: 2,
bar: 3
}
