Arrow function in javascript
// Arrow functions let us omit the `function` keyword. // Here `long_example` points to an anonymous function value. const long_example = (input1, input2) => { console.log("Hello, World!"); const output = input1 + input2; return output; }; // If there are no braces, the arrow function simply returns the expression // So here it's (input1 + input2) const short_example = (input1, input2) => input1 + input2; long_example(2, 3); // Prints "Hello, World!" and returns 5 short_example(2, 5); // Returns 7 // If an arrow function only has one parameter, the parentheses can be removed. const no_parentheses = input => input + 2; no_parentheses(3); // Returns 5
