JUnit исходный код плагина Eclipse?

Принятый ответ возвращает объект. Вы можете сделать что-то подобное, используя reduce , чтобы получить желаемый результат: 

const res=[{"url":"/page1","views":2},{"url":"/page2","views":1},{"url":"/page1","views":10},{"url":"/page2","views":4},{"url":"/page3","views":1},{"url":"/page2","views":0},{"url":"/page3","views":14},{"url":"/page1","views":04},{"url":"/page3","views":14}],

merged = res.reduce((acc,{url,views})=> {
    acc[url] = acc[url] || {url, views:0}
    acc[url].views += views;
    return acc;
}, {}),

output = Object.values(merged)
console.log(output)

Вот более короткая версия приведенного выше кода: 

const res=[{"url":"/page1","views":2},{"url":"/page2","views":1},{"url":"/page1","views":10},{"url":"/page2","views":4},{"url":"/page3","views":1},{"url":"/page2","views":0},{"url":"/page3","views":14},{"url":"/page1","views":04},{"url":"/page3","views":14}],

output = res.reduce((acc,{url,views})=>
    ((acc[url] = acc[url] || {url, views:0})["views"] += views, acc), {})
console.log(Object.values(output))

Другой вариант с использованием Map 

const res=[{"url":"/page1","views":2},{"url":"/page2","views":1},{"url":"/page1","views":10},{"url":"/page2","views":4},{"url":"/page3","views":1},{"url":"/page2","views":0},{"url":"/page3","views":14},{"url":"/page1","views":04},{"url":"/page3","views":14}],

map = res.reduce((m,{url,views})=> {
    const o = m.get(url) || {url,views:0};
    o.views += views;
    return m.set(url, o);
}, new Map),

output = [...map.values()];
console.log(output)
