Your two functions are identical.

const sum1 = function(list, prop){ return list.reduce( function(a, b){ return a + b[prop];}, 0);};

const sum2 = (list,prop) =>  { return list.reduce((a,b) => {return (a+ b[prop])}, 0)};

const list = [{foo:1},{foo:2},{foo:3}]

console.log(sum1(list, 'foo'));
console.log(sum2(list, 'foo'));

How To Convert Any Function To An Arrow Function In JavaScript

December 1, 2012 - For the right side of the arrow: If the function only returns an expression, then you can remove the “return” keyword along with the curly braces around the function body. In this case, the result of the expression will be automatically returned. If the returned expression is too large to fit in a single line, you can use parentheses around it. This is especially more commonly used in React.js development. Following the steps above, you can fully convert your traditional function into an arrow function.

Understanding Regular Function & Converting To Arrow Function

August 6, 2020 - We just need to “call” the function whenever we need the code we “saved” inside it to be executed anywhere in our project or program. Regular function has been in use since the initial stage of javascript. Arrow function on the other hand was introduced in the ES6 version of javascript.

Converting ECMAScript 6's arrow function to a regular function

An arrow function can usually be converted by replacing

(<args>) => <body>

with

function(<args>) { return <body>; }

So yours would be

rowCheckStatuses.reduce(function(a, b) { return a + b; }, 0)

There are exceptions to this rule so it's important that you read up on arrow functions if you want to know all of the differences. You should also note that arrow functions have a lexical this.

You can refactor it as:

if( rowCheckStatuses.reduce(function(a, b){return a + b}, 0)

The initial accumulator isn't necessary (unless you expect the array to be empty sometimes), it could be:

if( rowCheckStatuses.reduce(function(a, b){return a + b})

This number acts as a boolean to determine whether or not there is at least one "1" in the array

It might be faster (and clearer) to use:

if( rowCheckStatuses.some(function(a){return a == 1}))

which will return true if there are any 1s in rowCheckStatuses and will return as soon as one is encountered. Another alternative is indexOf:

if( rowCheckStatuses.indexOf(1) != -1)

Lots of alternatives.

angular - Javascript Convert function to arrow function - Stack Overflow

You need no curly brackets, and no this for the console.

this.$scope.$watch(
    () => this.$location.path(),
    value => console.log(value)
);

There is no need to wrap location.path into another function. Also you could access console without this.

// no need to wrap single parameter like `(value)` for your tsLint config.
this.$scope.$watch(this.$location.path, value =>{
   //this from parent

})

How to convert Arrow function to regular function [closed]

To convert an arrow function to non-arrow, you need to give it a name:

function mysumfunc (sum, li) {
    return sum + li.total;
};

To understand better the JavaScript reduce, see this more explicit example:

const array1 = [1, 2, 3, 4];

// 0 + 1 + 2 + 3 + 4
const initialValue = 0;
const sumWithInitial = array1.reduce(
  (previousValue, currentValue) => previousValue + currentValue,
  initialValue
);

typescript - How to convert function to arrow function in TS - Stack Overflow

Your attempt was close, but you forgot to include the generic argument declaration in front of the arrow function parameters. Try something like this:

const log = <T>(message: T): IO<void> =>
   new IO(() => console.log(message));

If you're working in a .tsx file, you may need to do something a little more complex to make it work.

You could try to use:

const log = <T>(message: T): IO<void> => new IO(() => console.log(message));
