Functions

  • spliceArray( target, source, start, count ) → Array<T>

    See source

    Splices one array into another. To be used instead of Array.prototype.splice as the latter may throw "Maximum call stack size exceeded" when passed huge number of items to insert.

    Note: in contrary to Array.splice, this function does not modify the original target.

    spliceArray( [ 1, 2 ], [ 3, 4 ], 0, 0 );	// [ 3, 4, 1, 2 ]
spliceArray( [ 1, 2 ], [ 3, 4 ], 1, 1 );	// [ 1, 3, 4 ]
spliceArray( [ 1, 2 ], [ 3, 4 ], 1, 0 );	// [ 1, 3, 4, 2 ]
spliceArray( [ 1, 2 ], [ 3, 4 ], 2, 0 );	// [ 1, 2, 3, 4 ]
spliceArray( [ 1, 2 ], [],       0, 1 );	// [ 2 ]
