echma 6 return type function code example
Example 1: arrow function map js
const exampleArray = ['aa','bbc','ccdd'];
console.log(exampleArray.map(a => a.length));
//Would print out [2,3,4]
Example 2: arrow function
// Traditional Function
function (a){
return a + 100;
}
// Arrow Function Break Down
// 1. Remove the word "function" and place arrow between the argument and opening body bracket
(a) => {
return a + 100;
}
// 2. Remove the body brackets and word "return" -- the return is implied.
(a) => a + 100;
// 3. Remove the argument parentheses
a => a + 100;
