How to get the middle words of a string in Node.js

Answer 1

function getMiddleWords(string) {
    // Split the string into an array of words
    const wordsArr = string.split(' ');
    const numWords = wordsArr.length;

    if (numWords % 2 === 0) {
        const middle1 = wordsArr[Math.floor(numWords / 2) - 1];
        const middle2 = wordsArr[Math.floor(numWords / 2)];
        return middle1 + ' ' + middle2;
    } else {
        const middle_minus_1 = wordsArr[Math.floor(numWords / 2) - 1];
        const middle = wordsArr[Math.floor(numWords / 2)];
        const middle_plus_1 = wordsArr[Math.floor(numWords / 2) + 1];
        return middle_minus_1 + ' ' + middle + ' ' + middle_plus_1;
    }
}

const string = "c++ c node.js rust c# python golang";

console.log(getMiddleWords(string));
