Usage

1var toDeduped = require( '@stdlib/array-base-to-deduped' );

toDeduped( x, limit, equalNaNs )

Copies elements to a new "generic" array after removing consecutive duplicated values.

1var x = [ 1, 1, 2, 3, 3 ];
2
3var y = toDeduped( x, 1, false );
4// returns [ 1, 2, 3 ]
5
6var bool = ( x === y );
7// returns false

When equalNaNs is false, NaN values are considered distinct, and, when equalNaNs is true, NaN values are considered equal.

1var x = [ NaN, NaN, 2, NaN, NaN ];
2
3var y1 = toDeduped( x, 1, false );
4// returns [ NaN, NaN, 2, NaN, NaN ]
5
6var y2 = toDeduped( x, 1, true );
7// returns [ NaN, 2, NaN ]

To allow consecutive duplicate values up to a specified limit, provide a limit argument greater than one.

1var x = [ 1, 1, 1, 2, 2, 3, 3, 3 ];
2
3var y = toDeduped( x, 2, false );
4// returns [ 1, 1, 2, 2, 3, 3 ]
