### Create and Initialize DataTable

Source: https://github.com/datatables/datatablessrc/blob/master/test/performance/common.txt

This snippet initializes a DataTable with a large dataset. Ensure the DOM element with id 'example' exists and DataTables library is included.

```javascript
let table;
	let columns = 30;
	let rows = 2500;
	let runs = 15;

	it('Create the table', function() {
		let header = '';
		for (let i = 0; i < columns; i++) {
			header += '<th>' + i + '</th>';
		}
		$('#example').append('<thead><tr>' + header + '</tr></thead>');

		let data = [];
		for (let i = 0; i < rows; i++) {
			let line = [];
			for (j = 0; j < columns; j++) {
				line.push(i + '-' + j);
			}
			data.push(line);
		}

		table = $('#example').DataTable({
			data: data
		});

		expect(table.page.info().recordsTotal).toBe(rows);
	});
```

### Basic JavaScript Initialization

The core JavaScript code used to initialize the DataTables instance for the example.

```javascript
{js-esc}
```

--------------------------------

### Clone and Build DataTables Source

Source: https://github.com/datatables/datatablessrc/blob/master/Readme.md

Clone the DataTables source repository, install dependencies, and build the project for local development.

```bash
git clone https://github.com/DataTables/DataTablesSrc.git

cd DataTablesSrc

npm install
npm run build-debug
npm serve
```

--------------------------------

### Initialize DataTables with Libraries

Source: https://github.com/datatables/datatablessrc/blob/master/build/templates/example.html

This snippet shows the basic initialization of DataTables, specifying libraries and a run function for custom JavaScript logic.

```javascript
dt_demo.init({ libs: {libs}, run: function () { {js} } });
```

--------------------------------

### Load DataTables Libraries and CSS

Source: https://github.com/datatables/datatablessrc/blob/master/test/performance/current.txt

Loads the necessary jQuery, DataTables JavaScript, and CSS files for testing. Ensure these are available in your project.

```javascript
dt.libs({
		js: ['jquery', 'datatables'],
		css: ['datatables']
	});
```

--------------------------------

### Check DataTables Version

Source: https://github.com/datatables/datatablessrc/blob/master/test/performance/old.txt

Asserts that the loaded DataTables version is '2.1.0'. This is useful for ensuring the correct library version is being tested.

```javascript
describe('performance', function() {
	dt.libs({
		js: ['jquery', 'datatables210'],
		css: ['datatables210']
	});

	dt.html('empty_no_header');
	it('Check this is the old version', function() {
		expect($.fn.dataTable.version).toBe('2.1.0');
	});
});
```

--------------------------------

### Generate Empty HTML for Testing

Source: https://github.com/datatables/datatablessrc/blob/master/test/performance/current.txt

Generates an empty HTML structure for DataTables, specifically without a header, to facilitate testing scenarios.

```javascript
dt.html('empty_no_header');
```

--------------------------------

### Additional CSS for Table Styling

Source: https://github.com/datatables/datatablessrc/blob/master/build/templates/example.html

Custom CSS rules applied to enhance the table's appearance beyond the default library styles.

```css
{css-esc}
```

--------------------------------

### Order DataTable Rows Ascending (Repeat)

Source: https://github.com/datatables/datatablessrc/blob/master/test/performance/common.txt

This test orders the DataTable rows in ascending order again. It's part of a loop to repeatedly test sorting responsiveness.

```javascript
it('Do something in the browser', function() {
			table.order([0, 'asc']).draw();
		});
```

--------------------------------

### Select Cells by Row Order

Source: https://github.com/datatables/datatablessrc/blob/master/test/performance/common.txt

This snippet selects cells based on the applied row ordering. It verifies that cell selection works correctly with ordered data.

```javascript
it('Cells - order [' + i + ']', function() {
			var rowIndexes = table
				.rows(null, { order: 'applied' })
				.indexes()
				.toArray();
			var cells = table.cells(rowIndexes, null, { order: 'applied' });

			expect(table.page.info().recordsTotal).toBe(rows);
		});
```

--------------------------------

### Select Cells by Column Order

Source: https://github.com/datatables/datatablessrc/blob/master/test/performance/common.txt

This snippet selects cells based on the applied column ordering. It confirms that cell selection respects column sorting.

```javascript
it('Columns [' + i + ']', function() {
			var columnIndexes = table
				.columns({ order: 'applied' })
				.indexes()
				.toArray();
			var cells = table.cells(columnIndexes, null, { order: 'applied' });

			expect(table.page.info().recordsTotal).toBe(rows);
		});
```

--------------------------------

### Check DataTables Version

Source: https://github.com/datatables/datatablessrc/blob/master/test/performance/current.txt

Verifies that the loaded DataTables version is not the specific older version '1.10.18'. This test is useful for ensuring compatibility or avoiding known issues with older versions.

```javascript
it('Check this is the old version', function() {
		expect($.fn.dataTable.version).not.toBe('1.10.18');
	});
```

--------------------------------

### Select Cells by Search Applied

Source: https://github.com/datatables/datatablessrc/blob/master/test/performance/common.txt

This snippet selects cells based on the applied search filter. It verifies that cell selection functions correctly with filtered data.

```javascript
it('Cells - search [' + i + ']', function() {
			var rowIndexes = table
				.rows(null, { order: 'applied' })
				.indexes()
				.toArray();
			var cells = table.cells(rowIndexes, null, { search: 'applied' });

			expect(table.page.info().recordsTotal).toBe(rows);
		});
```

--------------------------------

### Order DataTable Rows

Source: https://github.com/datatables/datatablessrc/blob/master/test/performance/common.txt

This test orders the DataTable rows in descending order. It's used to ensure responsiveness during sorting operations.

```javascript
it('Do something in the browser', function() {
			table.order([0, 'desc']).draw();
		});
```

--------------------------------

### Order DataTable Rows Ascending

This test orders the DataTable rows in ascending order. It's used to ensure responsiveness during sorting operations.

```javascript
it('Do something in the browser to stop timeout', function() {
			table.order([0, 'asc']).draw();
		});
```
