replace string using array in javascript

abc1 abc2 abc3
abc4 abc5 abc6
abc7 abc8 abc9
using above csv file, load text by replacing the double quotes from the bellow sentence.
Sentence:
"" is going with "" to "" for something to know.
Expected out put is:
abc1 is going with abc2 to abc3 for something to know.
abc3 is going with abc5 to abc6 for something to know.
like this in javascript, php.
Code I have tried so far:
var s = 'Neque porro "" estqui "" dolorem';
var insert = [["a1", "b1"]["c1","d1"]];
console.log(insert);
var words = new Array();
words = s.split(" ");
console.log(words);
var count = 0;
for (i = 0; i < words.length; i++) {
for (j = 0; j < insert.length; j++) {
if(words[i] == '""')
s = s.replace(/""/, insert[j]);
}
}
console.log(s);

Hurray I got the answer:
reader.onload = function (e) {
var sent = ''; var sentt = ''; var senttt = '';
sent = $('#mixmsg').val();
var quoteLength = (sent.match(/""/g) || []).length;
var rowcells = [];
rows = e.target.result.split("\n"); alert(rows);
for (var i = 0; i < rows.length; i++) {
var cells = rows[i].split(",");
rowcells.push(cells);
}
var rowcellso = rowcells.slice(0, -1);
console.log(rowcellso);
for (var ro = 0; ro < rowcellso.length; ro++) {
for (var scol = 0; scol < quoteLength; scol++) {
sent = sent.replace(/""/,rowcellso[ro][scol]);
console.log(rowcellso[ro][scol]);
} sentt +=sent+'\n'; sent= $('#mixmsg').val();
}
$('#container').html(sentt);
}

Javascript: Calculating Min/Max/Average

I wrote this code in my html site, in Javascript, but is not working right. Most times it seems to ignore some entries and just randomly selects which is the min/max value. Also, when I tried to calculate average values, I got a string instead of a number, even though the variable is declared as 0 in the beginning. e.g performing 0+1+1+2+3+5 = 011235 instead of 12.
Here is the code, thanks in advance.
**EDIT: I added the student average code in the end, but it doesn't work, it doesn't show any results on the page, not even the "student" + [i] part. On the other hand, the parseInt() command worked, and made everything work as it should, thank you :)

The value of an input is a string, thus a + b will be interpreted as appending one string to another.
If you make sure the first parameter (a in this case) is an integer a + b will result in the two being mathematically adding the two
console.log( '0' + 1 + 2 + 3 + 4 ); //* outputs 01234
console.log( parseInt( 0 ) + 1 + 2 + 3 + 4 ); //* outputs 10
JSFiddle

Ok for a start you seem very confused about
document.getElementById
This does not address a javascript variable at all......
This literally "gets the document element by its id".
Here is an example of how to use it...
<html>
<img id='my_new_selfie' src='me.jpg'>
....
....
<script>
alert (document.getElementById('my_new_selfie').src)
</script>
This would simply pop up an alert with the text that describes the src of the
document object who's id is 'my_new_selfie'
that is....
[me.txt]
The reason that document.getElementById was introduced to javascript was to save developers learning the DOM (document object model) in order to access objects.
It allows you to simply give you object an id and change things about it using the id
In the above example I could use a script or button to change the image source
an example of this might be using the onclick event of another object on the page like a button...
onclick='document.getElementById('my_new_selfie').src='new_pic_of_me.JPG'
It is not used to identify variables in a javascript

How do i display the longest array in JS?

I want to create a Javascript array of words, then use Javascript to find the longest word and print it to the screen. Here is my code:
var StrValues = []
StrValues[0] = ["cricket"]
StrValues[1] = ["basketball"]
StrValues[2] = ["hockey"]
StrValues[3] = ["swimming"]
StrValues[4] = ["soccer"]
StrValues[5] = ["tennis"]
document.writeln(StrValues);

You can use length to find the longest string in a array. Here is a fiddle http://jsfiddle.net/2sebnb33/1/
for(var i=0;i<StrValues .length;i++){
if(StrValues [i].length>len){
len=StrValues [i].length;index=i;}
}

var strValues = ["cricket", "basketball", "hockey"];
var max = '';
for(var i = 0; i< strValues.length; i++) {
max = strValues[i].length > max.length ? strValues[i] : max;
}
alert(max);

Firstly, you need to correct the way you are creating array.
For instance, it should be like this
var StrValues = [];
StrValues[0] = ["cricket"];
The logic
var longestWord = "";
for (var i = 0 ; i < StrValues.length; i++) {
if(StrValues[i].length > longestWord.length) {
longestWord = StrValues[i];
}
}

See the code below:
var array = [];
array.push("cat");
array.push("children");
array.push("house");
array.push("table");
array.push("amazing");
var maxSize = 0;
var maxSizeWord = "";
for(var i = 0; i < array.length; i++) {
if (maxSize < array[i].length) {
maxSize = array[i].length;
maxSizeWord = array[i];
}
}
alert("The biggest word is '" + maxSizeWord + "' with length '" + maxSize + "'!");

making groups with random names in it in javascript

I am new to coding Javascript. I am trying to to shuffle list of names inputted on a textarea. The user selects the number of groups desired, and shuffle on click, then show the divided groups as output result. Below is my code but it is not working as it should be, pls help!
<script>
function ArrayToGroups(source, groups){
var groupList = [];
groupSize = Math.ceil(source.length/groups);
var queue = source;
for(var r = 0; r < groups; r++){
groupList.push(queue.splice(0,groupSize));
}
return groupList;
}
function textSpliter(splitText){
var textInput = document.getElementById("inputText").value;
var splitText = textInput.split(',');
var newList = [];
for(x = 0; x <= splitText.length; x++) {
var random = Math.floor(Math.random() * splitText.length);
var p = splitText[random];
newList.push(p);
splitText.splice(p,groupList);
}
for(var i = 0; i < newList.length; i++){
var s = newList[i];
document.getElementById('resInput').value += s + "\n" ;
}
return splitText;
}
</script>
Below is my input and output textareas
</head>
<body>
<form>
<textarea id="inputText" placeholder="text" rows="10" cols="40"></textarea>
<input type="number" name="number" max="6" value="1" id="groupNumber">
<textarea id="resInput" placeholder="text" rows="10" cols="40"></textarea>
<input type="button" name="Shuffle" value="shuffle" onclick="textSpliter()">
</form>
</body>
</html>

function shuffle() {
// Get list
// Example: element1, element 2, ele ment 3, ...
var list = document.getElementById("inputText").value.replace(/\s*,\s*/g, ",").split(",");
// Get number of groups
var n = parseInt(document.getElementById("groupNumber").value);
// Calculate number of elements per group
var m = Math.floor(list.length / n);
// Enought elements
if (n * m == list.length) {
// Create groups
var groups = new Array();
for (i = 0; i < n; i++) {
groups[i] = new Array();
for (j = 0; j < m; j++) {
// Random
rand = Math.floor(Math.random() * list.length);
// Add element to group
groups[i][j] = list[rand];
// Remove element to list
list.splice(rand, 1);
}
}
// Output
var text = "";
for (i = 0; i < n; i++) {
text += "Group " + (i + 1) + ": ";
for (j = 0; j < m; j++) {
if (j != 0) { text += ", "; }
text += groups[i][j];
}
text += "\n";
}
document.getElementById("resInput").value = text;
} else {
alert("Add more elements");
}
}

I rewrote your code. It's pretty self-explanatory.
FIDDLE
function textSpliter() {
var input = document.getElementById("inputText").value;
var names = input.split(",");
var groupSize = document.getElementById("groupNumber").value;
var groupCount = Math.ceil(names.length / groupSize);
var groups = [];
for (var i = 0; i < groupCount; i++) {
var group = [];
for (var j = 0; j < groupSize; j++) {
var random = Math.floor(Math.random() * names.length);
var name = names[random];
if (name != undefined) {
group.push(name);
names.splice(names.indexOf(name), 1);
}
}
group.sort();
groups.push(group);
}
printGroups(groups);
}
function printGroups(group) {
var output = document.getElementById("resInput");
output.value = "";
for (var i = 0; i < group.length; i++) {
var currentGroup = "";
for (var j = 0; j < group[i].length; j++) {
currentGroup = group[i].join(",");
}
output.value += currentGroup + "\r";
}
}

ES6 version ;-)
http://jsfiddle.net/dLgpny5z/1/
function textSpliter() {
var input = document.getElementById("inputText").value;
var names = input.replace(/\s*,\s*|\n/g, ",").split(",");
var groupSize = document.getElementById("groupNumber").value;
var groupCount = Math.ceil(names.length / groupSize);
var groups = [...Array(groupCount)].map(() => Array());
var i = 0
while (names.length > 0) {
var m = Math.floor(Math.random() * names.length);
groups[i].push(names[m]);
names.splice(m, 1);
i = (i >= groupCount - 1) ? 0 : i + 1
}
printGroups(groups);
}
function printGroups(groups) {
var output = document.getElementById("resInput");
output.value = groups.map(group => group.join(',')).join('\r');
}

Javascript - String split does not work well

I am making a script which receives a String and separate it on smaller Strings.
Ex: "This is a long sentence, and I will separate it into smaller parts. Lalala"
It will return "This is a long sentence","and I will separate it into smaller parts","Lalala"
The aim of this is to use Google translator to transform text to speech, but this feature has a limit of about 70-80 chars, so if the string is too large I need to chop it.
First I chop in sentences separated by a dot ("."), then if there are still too long sentences, I split them with the commas (",") and if there are still too long strings I separate them in unique words.
Everything works well until I try to join some words so the audio become more continuous. For some reason the strings separated by commas get joined again. I do not know why.
This is the code:
Edit: Relevant section split out and formatted
function talk(text){
var audios = document.createElement('audio');
audios.setAttribute('id','audio_speech');
var playlist = new Array()
if(text.length >= 75) {
playlist = text.split(".");
for (var i = 0;i<playlist.length;i++) {
if (playlist[i].length >= 75) {
auxarr = playlist[i].split(",");
//alert(auxarr.length);
for(var j=0;j<auxarr.length;j++) {
auxarr2 = auxarr[j].split(" ");
document.write(auxarr2+"<br>");
if (auxarr[j].length >= 75) {
auxarr2 = auxarr[j].split(" ");
for(var x=0; x < auxarr2.length; x++){
if(auxarr2[x].length < 50) {
aux = auxarr2[x];
while (aux.length < 50 && auxarr2[x+1]) {
