JavaScript How to execute a loop with sequential summation? execute loop in postgresql,execute loop in sql,execute loop

You just need to move the console.log up one line. If you want the 28 to be logged also, then add a console.log(sum) after the loop.

var arr = [5, 4, 9, 6, 4];

var sum = 0;

arr.forEach(function(item) {
  console.log(sum)
  sum += parseInt(item);
});
Answer:1

You could add the value to a sum and make the sum usable in the next loop.

This solution uses a take first approach and changes a value later in the run.

[value, changePart][index]

var array = [5, 4, 9, 6, 4],
    result = array.map((s => v => [s, s += v][0])(0));
    
console.log(...result);
Answer:2

Just reorder some codes like this:

    var arr = [5, 4, 9, 6, 4];
        
    var sum = 0;
        
    arr.forEach(function(item) {
      console.log(sum)
      sum += parseInt(item);
    });
Answer:3
var arr = [5, 4, 9, 6, 4];

var sum = 0;

arr.forEach(function(item) {
  console.log(sum)
  sum += parseInt(item);
});

Simple display your counter before you interfere with it. You result will always start with 0 though since you define sum to be 0 before your loop.

Your output now should look like what you asked.

Answer:4

First log the sum value

var arr = [5, 4, 9, 6, 4];

var sum = 0;

arr.forEach(function(item) {
  console.log(sum)
  sum += parseInt(item);
});
Answer:5

As mentioned in a comment, just move up the console log line, that gets you what you declared your desired outcome.

const arr = [5, 4, 9, 6, 4];
    
let sum = 0;
    
arr.forEach(function(item) {
  console.log(sum);
  sum += parseInt(item);
});
Answer:6

Well, you can do that in a lot of different ways. Moving console.log one line up can be one. However, if you don't want to move your console.log, please refer to the below code where I used two sum variables:

var arr = [5, 4, 9, 6, 4];

var sum = 0;
var sum2 = 0;

arr.forEach(function(item) {
  sum += sum2;
  sum2 = parseInt(item);
  console.log(sum)
});
