calculate

Performs a mathematical operation (add, subtract, multiply, divide, mod) on an array of numbers.

Note: Requires at least two values. Division or modulo by zero will throw an error.

Parameters

• operation ('add' | 'subtract' | 'multiply' | 'divide' | 'mod'): The type of operation to perform.
• values (number[]): An array of numbers to operate on (minimum of 2).

Throws

• Error: If fewer than two numbers are provided.
• Error: If attempting to divide or modulo by zero.

Returns

• { result: number, type: OperationType }: The result of the operation and the operation type.

Usage

calculate('add', [1, 2, 3]);
// { result: 6, type: 'add' }

calculate('subtract', [10, 4]);
// { result: 6, type: 'subtract' }

calculate('multiply', [2, 3, 4]);
// { result: 24, type: 'multiply' }

calculate('divide', [20, 2]);
// { result: 10, type: 'divide' }

calculate('mod', [10, 3]);
// { result: 1, type: 'mod' }

calculate('divide', [5, 0]);
// ❌ Error: Division by zero
