## Изменение стилей на основе данных
|
||
|
||
Напомните себе еще раз, какова функция обратного вызова с [этим](https://codeburst.io/javascript-what-the-heck-is-a-callback-aba4da2deced)
|
||
|
||
Существует два способа завершить эту часть: либо с логикой if-else, либо с тройным оператором.
|
||
|
||
**логика if-else**
|
||
|
||
Пример из [w3school](https://www.w3schools.com/js/js_if_else.asp)
|
||
|
||
\`\` \`Javascript
|
||
|
||
const money = 50;
|
||
|
||
если (деньги <50) {
|
||
|
||
возвращение «Я богатый»;
|
||
|
||
}
|
||
|
||
else {
|
||
|
||
верните «Я бедный»;
|
||
|
||
}
|
||
```
|
||
What you need to remember is the bracket that the if-else logic associate with, (argument) and {statement}

**Ternary operator**
|
||
|
||
A more detailed explanation [here](https://codeburst.io/javascript-the-conditional-ternary-operator-explained-cac7218beeff). Ternary operator is a lot more concise and quicker to remember for a simple true or false statement. Read [this](https://www.thoughtco.com/javascript-by-example-use-of-the-ternary-operator-2037394)
|
||
```
|
||
|
||
Javascript
|
||
|
||
состояние ? value if true: значение if false
|
||
```
|
||
For someone who still not sure here is a solution by using If-else statement
|
||
```
|
||
|
||
Javascript .style ("color", (d) => { если (d <20) { return 'red' } else { return 'green' } }) \`\` \` |
