import a cvs file with the headers name and age. return a array of objects with the name and age from each row of the cab in typescript

To achieve this, we can make use of the Papa Parse library which is a powerful CSV parser that supports TypeScript.

Step 1: Install Papa Parse via npm

index.tsx
npm install papaparse
22 chars
2 lines

Step 2: Import Papa Parse in your .ts file where you want to do the CSV parsing

index.tsx
import * as Papa from 'papaparse';
35 chars
2 lines

Step 3: Read the CSV file using Papa Parse's parse function.

index.tsx
const csv = 'name,age\nJohn,25\nSally,33\nLisa,27';
const results = Papa.parse(csv, {header: true});
console.log(results.data);
128 chars
4 lines

The header option in the parse function is set to true to take into account the headers in the CSV file.

Step 4: Format the output in an array of objects with the name and age properties.

index.tsx
const csv = 'name,age\nJohn,25\nSally,33\nLisa,27';
const results = Papa.parse(csv, {header: true});

const output = results.data.map(row => ({
  name: row.name,
  age: row.age
}));

console.log(output);
204 chars
10 lines

This will output the following array of objects:

index.tsx
[
  {name: "John", age: "25"},
  {name: "Sally", age: "33"},
  {name: "Lisa", age: "27"}
]
91 chars
6 lines

Note: This assumes that the CSV file is already loaded into memory as a string. If you want to load the CSV file dynamically in a web application, you can use the FileReader API to read the file as a Blob and then use Papa Parse's parse function to parse its contents.
