Why backtick (``) is important in JavaScript ?

Template literals allow developers to embed expressions inside a string using placeholders, which are denoted by ${expression}. This enables developers to create dynamic strings that can be computed at runtime, and include variables, functions, and even other template literals.

const a = 'first string';

const b = 'second string';

console.log(`this is combination of ${a} and ${b}`);

output: this is combination of first string and second string

Template literals also support multi-line strings, which are defined by enclosing the string in backticks instead of quotes. This eliminates the need to use escape characters (\n) to represent line breaks, making the code more readable and easier to maintain.

console.log(`this is combination of ${a}

            and ${b} and the text you are reading is coming

            in ${c} line.`);

output: this is combination of first string

      and second string and the text you are reading is coming

      in 3 line.
