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

Answer

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

✐ Examples

1 Convert Strings to Integers

In this example,

We have an array of strings named strArray containing string representations of integers.
We use the map function to transform each element of strArray to an integer using type assertion as unknown as number.
The resulting array intArray contains the converted integers.
We log the contents of intArray to demonstrate the conversion.

TypeScript Program

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

Output

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