Struct rslint_core::groups::errors::NoSparseArrays [−][src]
pub struct NoSparseArrays {}
Expand description
Disallow sparse arrays.
Sparse arrays are arrays with empty slots, they are denoted by extra commas, such as:
let foo = [,,];
let foo = [bar,, baz];
Sparse elements will be filled in as undefined elements and count towards array length. This is often a typo or is hard to comprehend and an explicit method should be used.
Invalid Code Examples
let foo = [,];
let bar = [foo,, bar];
Implementations
Trait Implementations
Check an individual node in the syntax tree.
You can use the match_ast
macro to make matching a node to an ast node easier.
The reason this uses nodes and not a visitor is because nodes are more flexible,
converting them to an AST node has zero cost and you can easily traverse surrounding nodes.
