"In computer science, <code>data structures</code> are things that hold data. JavaScript has seven of these. For example, the <code>Number</code> data structure holds numbers.",
"Let's learn about the most basic data structure of all: the <code>Boolean</code>. Booleans can only hold the value of either true or false. They are basically little on-off switches.",
"Computers are not inherently smart. Hence, javascript developers made it easy for us to represent data to computer. <code>Data</code> is anything that is meaningful to the computer.",
"In computer science, <code>Data types</code> are things that represent various types of data. JavaScript has seven data types which are <code>Undefined</code>, <code>Null</code>, <code>Boolean</code>, <code>String</code>, <code>Symbol</code>, <code>Number</code>, and <code>Object</code>. For example, the <code>Number</code> data type represents numbers.",
"Now let's learn about the most basic one: the <code>Boolean</code> data type. Booleans represent a <code>true</code> or <code>false</code> value. They are basically little on-off switches.",
