Week 4 javascript challanges

*Console-Finances

Objective of this project is to write a block of code that would dynamically calculate and analyzes the records of an array of data. see the screen shot below:

** See live page at: https://zakaria1986.github.io/Console-Finances/

The dataset composed of 2 dimantional arrays set with two data field, which is: - Date -and Profit/Losses.

I was tasked with analyzing the records to calculate each of the following:

• The total number of months included in the dataset.

  // Iterate over the array and intrement by 1 to get the total number of months in the array ar totalMonth = 0; for (var i = 0; i < finances.length; ++i) { totalMonth += 1; }

• The net total amount of Profit/Losses over the entire period.

   /*
  
       - Create total place holder 
       - Put all the figures into one array; start by:
           - create an empty array
           - Loop over the sub arrays figuers 
               - push it to empty array
           
  
           - Write another loop to loop over the new array
           - then add the figures to total sum to get the lose/profile
   */
  
   // This solution worked out lot more simpler
   var profitLossTotal = 0;
   for (var arrayIndex = 0; arrayIndex < finances.length; arrayIndex++) {
       profitLossTotal += finances[arrayIndex][1];
   }
  

• The average of the changes in Profit/Losses over the entire period. - create a total prace holder - subract figers from month to month - Then find the average by deviding the tital with number of month i.e. total/number of month

var

tempfigureHolder,
negArray = [],
posArray = []
;

// Array seperating the positive and negative values for (var i = 0; i < finances.length; i++) {

if (finances[i][1] < 0) {
    negArray.push(finances[i][1]);
} else {
    posArray.push(finances[i][1]);
}

} // console.log(posArray + "\n\n");

// Looping throught the pogative array to find the differences

// Positive value variables var

posDiffTempPlaceHolder,
posDiff = [],
posTotal = 0;

for (var i = 0; i < posArray.length; i++) {

//  * Line below code checking to if there is next incremental item if false then return 0
var nextTotal = (posArray[i + 1] || 0) && posArray[i + 1];
posDiffTempPlaceHolder = (posArray[i] > nextTotal) ? posArray[i] - nextTotal : nextTotal - posArray[i];
posDiff.push(posDiffTempPlaceHolder);

} posDiff.pop(); for (var i = 0; i < posDiff.length; i++) {

posTotal += posDiff[i];

} // console.log("Pos array " + posArray); // console.log(posDiffTempPlaceHolder); // console.log(posDiff) // console.log(posTotal);

// Negative value variables var

negDiffTempPlaceHolder,
negDiff = [],
negTotal = 0;

for (var i = 0; i < negArray.length; i++) {

//  * Line below code checking to if there is next incremental item if false then return 0
var nextTotal = (negArray[i + 1] || 0) && negArray[i + 1];
negDiffTempPlaceHolder = (negArray[i] > nextTotal) ? negArray[i] - nextTotal : nextTotal - negArray[i];
negDiff.push(negDiffTempPlaceHolder);

}

negDiff.pop(); for (var i = 0; i < negDiff.length; i++) {

negTotal += negDiff[i];

}

// Total average avgTotalSum = 0; avgTotalSum = posTotal - negTotal; var avarage = avgTotalSum / totalMonth;

• The greatest increase in profits (date and amount) over the entire period.

• The greatest decrease in losses (date and amount) over the entire period.

The greatest increase in profits (date and amount) over the entire period. - Find the highest number - and then get console both date and the value // var testing =[1,2,3,4,5,6,71; newArray = []; var increased = 0; var maxValue = []; var minValue = "";

    for (var i = 0; i < finances.length; i++) {
        newArray.push(finances[i][1]);
        // get both value if it is the greatest value
    }

    var max = Math.max(...newArray);
    var min = Math.min(...newArray);
    for (var i = 0; i < finances.length; i++) {
        if (finances[i][1] === max) {
            maxValue = finances[i];
            console.log("max value", maxValue);

        }
        else if (finances[i][1] === min) {
            minValue = finances[i];
            //console.log(min);
            break;
        }
    }
