How to Use Escape Characters to Correctly Log Quotes in a String Using JavaScript?

Most developers face the issue of syntax errors when displaying log quotes in a string using the console.log() method. For instance, JavaScript provides three ways to write log quotes in a string using single quotes (‘ ‘), double quotes (“ ”), and backticks (` `). These quotes must be the same at both ends of the content to display it correctly. Moreover, the purpose of the quote is to nominate or highlight the message/information to the users.

This post provides a detailed demonstration of using the escape characters for quotes in a string by utilization of JavaScript.

How to Use Escape Characters to Quotes in a String?

The escape character is basically a backslash (\) that is utilized to display any character. The escape character is utilized to start the escape command to perform some tasks. The escape characters are required to display a quote in the console window. For example, \t for horizontal tab, \v for vertical tab, and \’ represent single quotation marks.

A string is a representation of a set of characters that are wrapped into quotes. In JavaScript, there is a constraint to printing a single or double quote at the same time. In the console method, if a string is presented in a single quote, then the user must utilize the double quote inside of the single quote or vice versa. Moreover, the backtick provides additional features to display single and double quotes at the same time in JavaScript.

Example 1: Use Escape Characters for Single Quotes

An example is adapted to use the escape characters as single quotes. For instance, the code is written below.

Code

console.log("An example of using single log quotes")

const eSingle = 'Welcome to \'JavaScript\'';

console.log(eSingle)

In this code, the eSingle variable is used to store the single quotes of a string by \’ and display it using the console.log() method in JavaScript.

Output

The output displays the message “Welcome to ‘JavaScript’ ”, in which JavaScript is highlighted within single quotes.

Example 2: Use Escape Characters to Double Quotes

Another example is following the steps to use the escape characters in the double quotes. The code is written below.

Code

console.log("An example of using double log quotes")

const eDouble = 'Welcome to "JavaScript"';

console.log(eDouble)

In this code, the eDouble variable is employed to store and display the string in double quotes.

Output

The output shows the highlighted word “JavaScript” within double quotes using escape characters.

Example 3: Use Escape Characters for Single and Double Quotes

In this example, backticks are adapted to display quotes in a string. It allows the user to use both double and single quotes. It is used as the outer quote. The code is given below.

Code

console.log("An example of using single and double log quotes")

const esd = `"Welcome' to "JavaScript"`;

console.log(esd)

In this code, the esd variable is used to store the single as well as double quotes present in the string by employing backticks.

Output

The output shows the execution of the above code to display single and double quotes in a string.

Conclusion

In JavaScript, single quotes (‘ ‘), double quotes (“ ”), and backticks(“) are employed for displaying correct log quotes in a string. For this purpose, the backslash \ escape character is utilized before single or double quotes of strings. In this article, you learned usage of escape characters for quotes in a string with JavaScript. In addition, both single and double quotes can be employed for a single-line string. For multiple lines, it is best practice to use the backticks.
