✐ 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 ofstrArray
to an integer usingparseInt
. - The resulting array
intArray
contains the converted integers. - 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 ]
