# add method

1. @Since.new('3.10')
2. @JS('push')

void add(

1. T value

)

Adds `value` to the end of this `Array`, extending the length by one.

## Implementation

    // This maps to `List.add` to avoid accidental usage of
    // `JSAnyOperatorExtension.add` when migrating `List`s to `JSArray`s. See
    // https://github.com/dart-lang/sdk/issues/59830.
    @Since('3.10')
    @JS('push')
    external void add(T value);
