用NodeJS计算JSON中的单词数

const fs = require('fs');

const content = fs.readFileSync('example.json');
const jsonObj = JSON.parse(content.toString());

const words = jsonObj.map(item => item.description.replace(/[^\w\s]/gi, '').split(' ')).flat();

const counts = words.reduce((acc, curr) => {
    acc[curr] = (acc[curr] || 0) + 1;
    return acc;
}, {});

console.log(counts);

{lorem: 3, ipsum: 2, dolor: 2, sit: 2, amet: 2, consectetur: 2, adipiscing: 1, elit: 1, Fusce: 1}
