JAVASCRIPT CODING: Converting a regular JavaScript function to the JavaScript arrow 🏹

Here we have two functions 𝙨𝙪𝙢𝙁𝙣 and 𝙨𝙪𝙢𝙁𝙣𝘼𝙧𝙧𝙤𝙬.

Both produce the same output:

// Javascript Function 

const sumFn = function(a,b) {

 return a + b; 

} 

// Javascript Arrow Function 

const sumFnArrow = (a,b) => a+b; 

console.log(sumFn(5,10)); //15

console.log(sumFnArrow(5,10)); //15 

Does anyone know how arrow function differs from the simple JavaScript function?
