NEW QUESTION # 69
What does a computer use to read and execute JavaScript code?

  • A. A validator
  • B. A virtual machine
  • C. A compiler
  • D. An interpreter

Answer: D

Explanation:
> "JavaScript is an interpreted programming language. The JavaScript engine within the browser (e.g., V8 for Chrome) parses and executes the JavaScript code line by line."

* MDN Web Docs: JavaScript Engine
* ECMAScript Language Specification

  • C. It specifies a CSS3 property.
  • D. It locates an HTML5 element by its ID

* Syntax: The ID selector is prefixed with a hash symbol (#) followed by the ID value of the HTML element.

width: 300px;

NEW QUESTION # 72
Given the following JavaScript code:
```javascript
<script>
var enabled = true;
</script>
```
Which code segment tests the variable value and displays an alert message?

  • A. ```javascript
    if enabled == true {
    alert('ok');
    }
    ```
  • B. ```javascript
    if enabled {
    alert('ok');
    }
    ```
  • C. ```javascript
    if(enabled){
    alert('ok');
    }
    ```
  • D. ```javascript
    if (enabled == true){
    alert('ok');
    }
    ```

Answer: C

Explanation:
> "The `if` statement in JavaScript requires parentheses around the condition. `if (enabled)` is a valid boolean condition and checks whether the variable `enabled` is truthy."
>
> "Using `if (enabled == true)` is redundant. The concise form `if (enabled)` is preferred." Correct Syntax:
if (enabled) {
alert('ok');
}
```

NEW QUESTION # 73
Which markup ensures that the data entered are either a five-digit zip code or an empty string?

  • A. Input required min=''s'' max=''s''
  • B. <input pattern=/d(5)''>
  • C. <input type=''number'' value=''s''
  • D. Input class ='' (0-9) (5)''>

Answer: B

Explanation:
The pattern attribute in the <input> element is used to define a regular expression that the input value must match for it to be valid. The pattern \d{5} ensures that the data entered is either a five-digit zip code or an empty string (if the required attribute is not used).
* Pattern Explanation:
* \d{5}: Matches exactly five digits.
* This ensures that only a five-digit number or an empty string (if not required) is valid.
* Usage Example:
<input type="text" pattern="\d{5}" placeholder="Enter a 5-digit zip code"> This ensures that the input matches a five-digit zip code.
