2. Double quotes

Double quotes (") can also be used to mark string constants. For example:

<code class="js">const greeting = "Hello, world!";</code>
Copy after login

3. Escape characters

Use escape characters () to escape special characters in strings, such as quotation marks and newlines. For example:

<code class="js">const escapedQuote = 'He said, "Hello, world!"';</code>
Copy after login

4. . Special characters

Certain characters, such as newlines and tabs, cannot be written directly in strings and can be escaped using special characters:

  • . \n: Newline character
  • \t: Tab character
  • \: Backslash
  • \': Single quote (in a single-quoted string)
  • \": Double quote (in a double-quoted string)

5. Multi-line string

To create a multi-line string, you can use backtick (`). For example:

<code class="js">const poem = `Roses are red,
Violets are blue,
Sugar is sweet,
And so are you.`;</code>
