Summary
Data types are the building blocks of programming. Primitive data types include numbers, strings, booleans, and BigInts. BigInts are used for larger numbers. Backticks are extended functionality quotes that allow us to embed variables and expressions into a string. For example, we can embed a variable by wrapping it in ${…}, such as let name = "John"; alert( `Hello, ${name}!` ); // Hello, John! We can also embed an expression, such as alert( `the result is ${1 + 2}` ); // the result is 3.
