In JavaScript, the second type of primitive data is the String type.
1. String Type
- A string in JavaScript is a sequence of characters enclosed in single quotes (
'), double quotes ("), or backticks (`). - Example: Declaring a String
let message = "hello coders";
// Print the string
document.write(message); // Output: "hello coders"Explanation:
- Here, the string
"hello coders"is stored in the variablemessage, and is displayed usingdocument.write().
2. String Concatenation
- In JavaScript, strings can be concatenated (joined) using the
+operator. - Example: Concatenating Strings
let name = "coders";
let message = "good evening";
// Concatenate the strings
let greet = "hello " + name + ", " + message;
document.write(greet); // Output: "hello coders, good evening"Explanation:
- We concatenate
"hello ",name, andmessageto create the final string"hello coders, good evening". This is achieved by using the+operator.
3. Template Literals with Backticks
- Using backticks (
`), we can embed variables and expressions directly inside a string. This method provides a cleaner way to combine strings and dynamic values without using concatenation. - Example: Using Backticks and Embedded Expressions
let name = "coders";
let message = "good evening";
// Use template literals and embedded variables
let greet = `hello ${name}, ${message}`;
document.write(greet); // Output: "hello coders, good evening"Explanation:
- In this example, backticks are used to create a template literal. Inside the template literal,
${}is used to embed the variablesnameandmessagedirectly into the string, resulting in"hello coders, good evening".
Summary:
- Strings are sequences of characters enclosed in quotes.
- Concatenation can be done using the
+operator. - Template literals (backticks) provide an easier way to embed variables and expressions into strings without concatenation.
