There is a special type of quotes - backticks:
let str = `abc`;
alert(str); // shows 'abc'
With backticks you can perform insertion of
variables. To do this, you need to write the
variable name in the construction ${}.
Let's look at an example. Let's say we want to add strings and a variable:
let str = 'xxx';
let txt = 'aaa ' + str + ' bbb';
This code can be rewritten like this:
let str = 'xxx';
let txt = `aaa ${str} bbb`;
Rewrite the following code, using variable insertion:
let str1 = 'xxx';
let str2 = 'yyy';
let txt = 'aaa ' + str1 + ' bbb ' + str2 + ' ccc';
