@ -109,7 +109,7 @@ Here, operators work one after another. The first `+` sums two numbers, so it re
```js run ```js run
alert('1' + 2 + 2); // "122" and not "14" alert('1' + 2 + 2); // "122" and not "14"
``` ```
Here, the first operand is a string, the compiller treats the other two operands as string too. The `2` gets concatinated to `'1'`, so it's like `'1' + 2 = "12"` and `"12" + 2 = "122"` Here, the first operand is a string, the compiler treats the other two operands as strings too.

The binary `+` is the only operator that supports strings in such a way. Other arithmetic operators work only with numbers and always convert their operands to numbers.
