Templated String Literals
JavaScript also supports templated string literals, which is where we insert a variable or expression into a string. We just use backticks instead of single or double quotes, and surround the variable name or expression with ${}. Example:
const a = 57;
const myStr = `The variable a is set to ${a}.`;
const myStr2 = `If we add ${a} and 73, we get ${a + 73}!`;
console.log(myStr);
console.log(myStr2);
> The variable a is set to 57.
If we add 57 and 73, we get 130!
This didn’t feel like it needed its own section, but I included this since many people don’t know that JavaScript supports them, and I use them in later examples.
