I don't know this can be possible or not I want to store all my condition in array and need to call it in if statement
const addition = (...numbers) => {
let arrayOfTest = [
`${numbers.length === 0}`,
`${numbers.some(isNaN)}`,
`${numbers === null}`,
];
if (arrayOfTest.includes(true)) {
throw new Error("Invalid Input");
} else {
return numbers.reduce((a, b) => {
return a + b;
});
}
};
console.log( addition(1, 3, 4, 5, 7, 8));
Is this possible? Can I write all my conditions in array list and call it in if statement
Don't enclose the boolean values in backticks, as that makes them strings.
const addition = (...numbers) => {
let arrayOfTest = [
numbers.length === 0,
numbers.some(isNaN),
numbers === null,
];
if (arrayOfTest.includes(true)) {
throw new Error("Invalid Input");
} else {
return numbers.reduce((a, b) => {
return a + b;
});
}
};
