Edit CSV
Edit CSV is a free online tool that allows users to edit CSV files through a table-based user interface. It offers features such as undo/redo functionality, column sorting by clicking on header text, and the ability to rearrange rows and columns by dragging. Users can resize rows and columns, and navigate efficiently using keyboard shortcuts to move to the first cell in a row, to move to the last cell, to jump to the first cell in a column, and to reach the last cell. You can also add a line break within a cell. To delete a row or column, hover over it and click the trash icon. Double-clicking a column's resize handle adjusts its width to fit the content; double-clicking an auto-sized column sets its width to 200px, which is useful for very wide columns. It also provides a context menu accessible via right-click and supports copy-pasting using the tab key as a separator, similar to Excel.

JavaScript
JavaScript is a scripting language and programming language for the web that enables developers to build dynamic elements on the web. Over 97% of the websites in the world use client-side JavaScript. JavaScript is one of the most important scripting languages on the web. Strings in JavaScript are contained within a pair of either single quotation marks '' or double quotation marks "". Both quotes represent Strings but be sure to choose one and STICK WITH IT. If you start with a single quote, you need to end with a single quote. There are pros and cons to using both IE single quotes tend to make it easier to write HTML within Javascript as you don’t have to escape the line with a double quote. Let’s say you’re trying to use quotation marks inside a string. You’ll need to use opposite quotation marks inside and outside of JavaScript single or double quotes.
