JavaScript const numbers: number[] = [4, 2, 7, 1, 9, 5]; numbers.sort((a, b) => a - b); console.log("Sorted Numbers: ", numbers); Output: Sorted Numbers: [1, 2, 4, 5, 7, 9]Sorting Array of Strings Example: In this example, we have an array of strings, and we use the sort method to sort the strings in default lexicographic order.

We use the sort method with a custom comparison function to sort the array based on the age property in ascending order. JavaScript interface Person { name: string; age: number; } const people: Person[] = [ { name: "Alice", age: 25 }, { name: "Bob", age: 30 }, { name: "Charlie", age: 22 }, { name: "David", age: 28 } ]; people.sort((a, b) => a.age - b.age); console.log("Sorted People by Age: ", people); Output: Sorted People by Age: [ { name: 'Charlie', age: 22 }, { name: 'Alice', age: 25 }, { name: 'David', age: 28 }, { name: 'Bob', age: 30 } ] Comment More infoAdvertise with us A amanv09 Follow Improve Article Tags : TypeScript Similar Reads TypeScript Tutorial TypeScript is a superset of JavaScript that adds extra features like static typing, interfaces, enums, and more.
