how 2+ +'2'=4 in js?

## 🗒️ Answer
In JavaScript, the expression `2+ +'2'` evaluates to `4` due to type coercion and unary plus operator:

1. The first `2` is a number.
2. The second `'2'` is a string.
3. The unary plus operator `+` before the second `'2'` coerces it into a number. Since it's a valid number representation, it becomes `2`.
4. Now the expression becomes `2 + 2`, which equals `4`.

So, `2+ +'2'` evaluates to `4` because JavaScript coerces the string `'2'` to a number using the unary plus operator[[1]
