【JavaScript】forEachメソッドをfilterメソッドで書き換える

forEachメソッドで書くと長くなるコードをfilterメソッドを使うと簡潔に書ける。

const words = ['spray', 'limit', 'elite', 'exuberant', 'destruction', 'present'];

const result = [];

words.forEach((element, i2) => {

    if (element.length > 6) {
        result.push(element);
    }

});

console.log("result = " + result);

const result2 = words.filter(word => word.length > 6);

console.log("result2 = " + result2);

/*

result = exuberant,destruction,present
result2 = exuberant,destruction,present

*/
