Tests:

[lambda] Array.find() > findBy
const findBy = (fn) => { return users.find(item => fn(item)) ?? null; } findBy(user => user.name === 'Yvonne');
[lambda] for..of > findBy
const findBy = (fn) => { for (const user of users) { if (fn(user)) { return user; } } return null; } findBy(user => user.name === 'Yvonne');
[no lambda] for..of > findByName
const findByName = (name) => { for (const user of users) { if (user.name === name) { return user; } } return null; } findByName('Yvonne');
[no lambda] for..of > findByKeyValuePair
const findByKeyValuePair = (key, value) => { for (const user of users) { if (user[key] === value) { return user; } } return null; } findByKeyValuePair('name', 'Yvonne');
[lambda] for-loop > findBy
const findBy = (fn) => { for (i = 0; i < users.length; ++i) { const user = users[i]; if (fn(user)) { return user; } } return null; } findBy(user => user.name === 'Yvonne');
[no lambda] for-loop> findByName
const findByName = (name) => { for (i = 0; i < users.length; ++i) { const user = users[i]; if (user.name === name) { return user; } } return null; } findByName('Yvonne');
[no lambda] for-loop > findByKeyValuePair
const findByKeyValuePair = (key, value) => { for (i = 0; i < users.length; ++i) { const user = users[i]; if (user[key] === value) { return user; } } return null; } findByKeyValuePair('name', 'Yvonne');
