How to Convert an Array of Strings to an Array of Integers in JavaScript ?

Answer

To convert an array of strings to an array of integers in JavaScript, you can use the `map` function along with `parseInt` to perform the conversion.



✐ Examples

1 Convert Strings to Integers

In this example,

  1. We have an array of strings named strArray containing string representations of integers.
  2. We use the map function to transform each element of strArray to an integer using parseInt.
  3. The resulting array intArray contains the converted integers.
  4. We log the contents of intArray to demonstrate the conversion.

JavaScript Program

const strArray = ["10", "20", "30"];
const intArray = strArray.map(str => parseInt(str));
console.log("Converted array of integers:", intArray);

Output

Converted array of integers: [ 10, 20, 30 ]
