Variable dropConst

Type Declaration

• • <const Ar extends readonly unknown[], N extends ArgArr>(
        array: Ar,
        num: N,
    ): HasLengthConstraint<Ar> extends true
        ? readonly Ar[number][]
        : N extends StructuralPrefixLength ? Skip<N, Ar> : readonly Ar[number][]

  • Skips the first N elements of an array.

    Type Parameters

    • const Ar extends readonly unknown[]
    • N extends ArgArr

    Parameters

    • array: Ar
    • num: N

    Returns HasLengthConstraint<Ar> extends true
        ? readonly Ar[number][]
        : N extends StructuralPrefixLength ? Skip<N, Ar> : readonly Ar[number][]

    Example

    const values = ['a', 'b', 'c', 'd'] as const;
    
    const withoutFirstTwo = Arr.skip(values, 2);
    
    const withoutFirstThree = Arr.skip(3)(values);
    
    assert.deepStrictEqual(withoutFirstTwo, ['c', 'd']);
    
    assert.deepStrictEqual(withoutFirstThree, ['d']);
