How to get element by id in javascript | JavaScript Tutorial
In this video we will explore how to use the get element by id command in Javascript. Commonly written as document.getElementById. The getElementById command is a way to communicate with the DOM object. Basically it will search for an element name with the id that you indicate.
But extracting the value of the ID itself will depend with different cases. If you work with a basic tag such as an div, paragraph or list you will use different commands and use the innerText to extract and display the text.
If you have input types of any kind you will be using the ".value" command together with the getElementById. The most important part is to know how to extract the text or value with the right codes. We will be covering both cases and eventually display it in a new class with the querySelector command. This will be fun and interesting!

Why did I created these Chart JS video tutorials?
Have you ever used Excel where charts appear almost magically with a click on a button. You notice if you look at a chart or graph you can absorb information within seconds which would take you minutes if it is a table with data.
"A picture is worth a thousand words"
We all know that pictures and colors spark the mind. However, if you try to draw or code a 📊 bar chart or a 📈 line chart, or any type of chart in a Javascript library it is a big challenge. The documentation makes it hard and the it is very hard to work with a canvas tag.
Ancient Egypt used hieroglyphs in their writing system. Which was both logical and creative at the same time. And this is why I love charts as well. A chart is the closes to translating logic into visuals. Making the chart interactive is the best way to communicate your message to others.
If we know about this why is coding charts so complicated?
Because computer programming language is based on 100% logic. This is why when you look at Chart.JS, D3.JS, Chartist and other chart libraries in JS you will need to basically explain in logic to a computer what to make visual.
How and where can I help?
