Prettier reformats if / else into single line

Prettier is a popular code formatting tool designed to help developers maintain code consistency and readability. In response to your query, Prettier's handling of if/else statements typically depends on several factors, including statement length and configuration options. By default, Prettier does not reformat if/else statements into single lines as it prioritizes code clarity and readability. For example, consider the following code:

javascript
if (condition) {
  doSomething();
} else {
  doSomethingElse();
}

After Prettier formatting, the code maintains the above structure and does not collapse into a single line. This is because the expanded format enhances readability, particularly when the if and else blocks contain multiple statements. However, for very simple if/else statements that contain only a single expression with no additional logic, Prettier will keep them on a single line. For example:

javascript
if (condition) doSomething(); else doSomethingElse();

In such cases, since the logic is simple, Prettier may choose to keep the code on a single line to minimize unnecessary line breaks. Overall, Prettier's main objective is to improve code readability and consistency, rather than unconditionally minimizing the number of lines. For specific formatting needs, Prettier allows customization via the .prettierrc file or other configuration options to achieve your preferred formatting.
