Concise Arrow Function Syntax

Arrow functions are already less verbose than function declarations and function expressions, but you can write them in a more concise way.

Arrow Functions with One Parameter

If your arrow function accepts a single argument, like the square function below, you can omit the parentheses:

const square = x => {
  return x * x;
}

square(10); // 100
