Question

How to sort an array of strings where each string represents a decimal number in Node.js

Answer 1

// Comparator function to sort strings as decimal numbers
function compareAsDecimal(a, b) {
    // Convert strings to numbers for comparison
    const numA = parseFloat(a);
    const numB = parseFloat(b);
    
    return numA - numB; 
}

// Input array of strings
const numbers = ["11.3", "3.6", "89.1", "3.14", "456.0", "0", "0.001", "2.0"];

// Sort the array using the custom comparator
numbers.sort(compareAsDecimal);

console.log("Sorted array of decimal strings:");
console.log(numbers.join(" "));




/*
run:

Sorted array of decimal strings:
0 0.001 2.0 3.14 3.6 11.3 89.1 456.0

*/
