The main syntax difference between traditional functions and fat-arrow functions lies in the use of the greater-than sign and equal sign (=>) as part of the fat-arrow function's declaration. This syntax allows developers to create functions more concisely without the need to use the `function` keyword, which is required in traditional function declarations.

For example, a traditional function could be defined as follows:

```javascript

function add(a, b) {

return a + b;

}

```

In contrast, a fat-arrow function for the same purpose can be expressed succinctly like this:

```javascript

const add = (a, b) => a + b;

```

The use of the fat-arrow syntax simplifies the function declaration and enhances readability, especially for inline functions or callbacks. While the other options touch upon aspects of function syntax, they do not capture this fundamental difference: the unique use of the fat-arrow notation (=>) is what distinguishes it from traditional function declarations.
