Discussion on: Stop using var for declaring variables !!!

View post

Replies for: There can be many examples. I can write an entire blog post about it 😅 There is a difference in the way JS engine treats var and let/const when it ...

var strings = [
    'Sometimes,',
    '`var` is best,',
    'whereas other times,',
    '`let` is best.',
]

for (var [idx, str] of strings.entries()) {
    setTimeout(() => console.log(str), idx * 1000)
}
