Creating multiline strings in JavaScript

In JavaScript, you can create multiline strings using template literals (also known as template strings). Template literals allow you to write multiline strings without the need for manual line breaks or concatenation.

Using Template Literals

Template literals are enclosed by backticks ( ) and can span multiple lines without the need for escape characters. You can interpolate variables or expressions directly into the string using ${}.

const multilineString = ` This is a multiline string. It can span multiple lines. You can interpolate variables like... `; console.log(multilineString);
//Output; This is a multiline string. It can span multiple lines. You can interpolate variables like...

Escaping Backticks

If your multiline string contains backticks and you need to include them as part of the string, you can escape them using a backslash (\).

const stringWithBacktick = ` This is a string with a backtick (\`). You can include it using the escape character. `; console.log(stringWithBacktick);
//Output; This is a string with a backtick (`). You can include it using the escape character.

Maintaining Indentation

Template literals preserve leading whitespace and indentation. If you want to remove the leading indentation from each line, you can use the .trim() method.

const indentedString = ` This string has indentation. It will be preserved in the output. `; const trimmedString = indentedString.trim(); console.log(trimmedString);
//Output; This string has indentation. It will be preserved in the output.

Remember that template literals are a feature introduced in ECMAScript 6 (ES6) and might not be supported in older browsers. However, they are widely supported in modern browsers and environments.

Conclusion

Using template literals to create multiline strings in JavaScript improves code readability and simplifies the process of working with strings that span multiple lines.
