Получение индекса по значению

[Янковиц]

Есть массив:

0: [href: "https://images.unsplash.com/photo-1430651717504-ebb9e3e6795e", id: "13", title: "Заголовок"]
1: [href: "https://images.unsplash.com/photo-1458400411386-5ae465c4e57e", id: "52", title: "Заголовок 2"]
2: [href: "https://images.unsplash.com/photo-1460500063983-994d4c27756c", id: "63", title: "Заголовок 3"]
3: [href: "https://images.unsplash.com/photo-1452473767141-7c6086eacf42", id: "47", title: "Заголовок 4"]

Как получить индекс, если известен href и он равен https://images.unsplash.com/photo-14...4-ebb9e3e6795e
заранее спасибо

console.log(
    [

    ].findIndex(el => el.href === "https://images.unsplash.com/photo-1430651717504-ebb9e3e6795e")
);

var indHref = (arr, hrf) => arr.findIndex(el => el.href === hrf);

Спасибо, работает. Однако в jS компрессоре ругается на строку:
indHref = (lbCollect, source) => lbCollect.findIndex(el => el.href === source);
Invalid assignment (line: 21, col: 32)
Делаю так:

source = [url]https://images.unsplash.com/photo-1430651717504-ebb9e3e6795e;[/url]
lbCollect = [
      {href: "https://images.unsplash.com/photo-1430651717504-ebb9e3e6795e", id: "13", title: "Заголовок"},
      {href: "https://images.unsplash.com/photo-1458400411386-5ae465c4e57e", id: "52", title: "Заголовок 2"},
      {href: "https://images.unsplash.com/photo-1460500063983-994d4c27756c", id: "63", title: "Заголовок 3"},
      {href: "https://images.unsplash.com/photo-1452473767141-7c6086eacf42", id: "47", title: "Заголовок 4"}
    ];
indHref = (lbCollect, source) => lbCollect.findIndex(el => el.href === source);

В общем, сделал так:

indHref = lbCollect.findIndex(function(object) {
	return object.href === source;
});
