JS Refactoring Combo: Simplify If-Else Variable Initialization

If-statements are often used to initialize variables with different values depending on a condition. This can lead to unnecessary code duplication and can often be shortened with the conditional operator.

Before (Example)

let movedObject; if (direction === "left") { movedObject = moveLeft(original); } else { movedObject = moveRight(original); } 

Refactoring Steps

💡  The refactoring steps are using P42 JavaScript Assistant v1.99.

1. Convert the if-else statement into a conditional expression
2. Merge variable declaration and initialization
3. Convert let to const

After (Example)

const movedObject = direction === "left" ? moveLeft(original) : moveRight(original); 

The change to const is only possible if the variable is not re-assigned later. It has the advantage that it communicates the immutability of movedObject.
