multiply all numbers in an array javascript
The cause is already known. Here's an alternative - using Array.reduce for your method: console.log( [1, 2, 3].reduce( (a, b) => a * b ) ); console.log( Array.from( {length: 20} ) .map( (v, i) => i + 1 ) .reduce( (a,b) => a * b ) .toLocaleString()); // for empty arrays, use some initial value const arr = []; if (arr.reduce( (a, b) => a * b, -1 ) === -1) { console.error(`The given array ${arr} is empty`); }
