I don`t understand where am i wrong?
var expect = require('chai').expect
describe('subtraction', function () {
var subtraction = require('../WHEREVER')
it('only works with numbers', function () {
let handel = function (){subtraction("la",12);};
expect(handel).to.throw(Error);
expect(handel).to.throw('subtraction only works with numbers!');
})
})
function subtraction (number1, number2) {
if (typeof number1 !== 'number' || typeof number2 !== 'number') {
throw Error('subtraction only works with numbers!')
}
return number1 - number2
