Hello

it is Array. var array1 = [];

$.("array1").each(function(idx, item){
var MateoName= item.Name;

var NoahSubject = getvalue(item, idx);
...........
});

Isn’t this how you do it?

var array is

1) How do I get Mateo of HeaderName?
var Name = array1.Get
2) How do I get Noah of Subject Name?
var Math = array1.Get

please answer me. I'm waiting for your reply.

You are conducting this with an incorrect approach! You merely need to use document.GetElementById. Perhaps .value regarding what you would like to accomplish!
JavaScript:
var Name = document.getElementById("array1").value;
var other = document.getElementById("array2").value;
//Unfamiliar with solution desired, or...
var Name = document.getElementById("array1");
var other = document.getElementById("array2");

Did you tried in that way

[ on-line ]
JavaScript:
const array1 = [
  { 'name':'James', 'subject':'English', 'score':80 },
  { 'name':'Mateo', 'subject':'Chinese', 'score':50 },
  { 'name':'Noah',  'subject':'Math',    'score':40 },
]

/* for demonstration */
const pre = document.createElement('pre');

pre.innerHTML = array1[0].name + ' ' + array1[0].subject;
pre.innerHTML += '\n';
pre.innerHTML += `${array1[0].name} ${array1[0].subject}`;

pre.innerHTML += '\n\n';

for (const row of array1) {
  pre.innerHTML += `${row.name}, ${row.subject}:${row.score}.\n`;
}

pre.innerHTML += '\n\n';

for (const index in array1) {
  pre.innerHTML += `${(index*1+1)}. ${array1[index].name} ${array1[index].subject}:${array1[index].score}.\n`;
}

document.body.appendChild(pre);
or
[ on-line ]
JavaScript:
const array1 = [
  [ 'James', 'English', 80 ],
  [ 'Mateo', 'Chinese', 50 ],
  [ 'Noah',  'Math', 40 ]
]

/* for demonstration */
const pre = document.createElement('pre');

pre.innerHTML = array1[0][0] + ' ' + array1[0][1];
pre.innerHTML += '\n';
pre.innerHTML += `${array1[0][0]} ${array1[0][1]}`;

pre.innerHTML += '\n\n';

for (const row of array1) {
  pre.innerHTML += `${row[0]}, ${row[1]}:${row[2]}.\n`;
}

pre.innerHTML += '\n\n';

for (const index in array1) {
  pre.innerHTML += `${(index*1+1)}. ${array1[index][0]} ${array1[index][1]}:${array1[index][2]}.\n`;
}

document.body.appendChild(pre);

Var length = array1.length is 10000
array1.length is 10000.
So, i hope to
for(int i=0; i< array1.length; i++) statement or $.each statement


I hope to
$.("array1").each(function(idx, item){
var MateoName= item.Name;

var NoahSubject = getvalue(item, idx);
...........
});

Can you show, how exactly looks you array, just few values, no need expose 10000 items.
array1.length is 10000.
because the image suggests that you have a table in Excel, or am I wrong?


BTW, 10000 is not a big length of array, that you should worry.
JavaScript:
console.time("preparing an array of length 10000"); // Start measuring the time

const array = new Array(10000).fill().map(() => {
  const min = 1, max = 10000;
  return Math.floor(Math.random() * (max - min + 1)) + min;
});

console.timeEnd("preparing an array of length 10000"); // End measuring the time and display the result in the console

console.log(array.length);

But this code example is Java not Javascript - this is not the same.
Any way, on the picture is how this array looks like
java-array-1.png

i can't see any connection to your previously example
array-1.png


sorry, I can't help you, to mach confused about what you exactly want to do.




and this one below is JQuery - is a popular JavaScript library that simplifies web development by providing a wide range of pre-built functions and features.
$.("array1").each(function(idx, item){
var MateoName= item.Name;

var NoahSubject = getvalue(item, idx);
...........
});
