No Variadic Spread

Error

small-rules/no-variadic-spread

Disallow spreading a potentially unbounded array into a variadic call, because every element becomes a stack-allocated argument.

Diagnostic Messages

noVariadicSpread

Spreading an array into {{method}}() passes every element as its own stack argument, so a large array throws 'RangeError: Maximum call stack size exceeded'. Iterate the array instead.

Configuration

This rule does not accept options.

Examples

Spreading an array into push()

target.push(...source);
