2.What is the correct JavaScript syntax to write "Hello World"?
technology programming languages

  1. response.write("Hello World")

  2. document.write("Hello World")

  3. ("Hello World")

  4. "Hello World"

Show answer
Correct Option: B
Explanation:

To write "Hello World" in JavaScript, the correct syntax is:

B. document.write("Hello World")

Explanation:

A. response.write("Hello World"): This is not the correct syntax. The "response" object does not have a "write" method in JavaScript.

B. document.write("Hello World"): This is the correct syntax. The "document" object represents the current web page, and the "write" method is used to write content directly to the web page. In this case, it will write "Hello World" to the page.

C. ("Hello World"): This is not the correct syntax. Parentheses alone do not have any specific meaning in JavaScript.

D. "Hello World": This is a string literal and is valid syntax in JavaScript. However, it does not actually write "Hello World" to the web page. It is just a static string value that can be assigned to a variable or used in other operations.

Therefore, the correct answer is B. document.write("Hello World").

technology databases

  1. INSERT NEW

  2. ADD NEW

  3. ADD RECORD

  4. INSERT INTO

Show answer
Correct Option: D

AI Explanation

To answer this question, you need to understand SQL statements for inserting new data into a database.

Let's go through each option to understand why it is correct or incorrect:

Option A) INSERT NEW - This option is incorrect because there is no SQL statement called "INSERT NEW" for inserting new data into a database.

Option B) ADD NEW - This option is incorrect because there is no SQL statement called "ADD NEW" for inserting new data into a database.

Option C) ADD RECORD - This option is incorrect because there is no SQL statement called "ADD RECORD" for inserting new data into a database.

Option D) INSERT INTO - This option is correct because the SQL statement "INSERT INTO" is used to insert new data into a database.

The correct answer is D) INSERT INTO. This option is correct because the "INSERT INTO" statement is commonly used in SQL to add new records to a database table.

With SQL, how do you select a column named 'FirstName' from a table named 'Persons'?

technology databases

  1. SELECT FirstName FROM Persons

  2. EXTRACT FirstName FROM Persons

  3. SELECT Persons.FirstName

  4. SELECT * FROM Persons

Show answer
Correct Option: A

AI Explanation

To select a column named 'FirstName' from a table named 'Persons' in SQL, you would use the SELECT statement. Let's go through each option to understand why it is correct or incorrect:

Option A) SELECT FirstName FROM Persons - This option is correct because it uses the SELECT statement to specify the column 'FirstName' that you want to retrieve from the table 'Persons'.

Option B) EXTRACT FirstName FROM Persons - This option is incorrect. The EXTRACT keyword is used to extract parts of a date or time value, not for selecting columns from a table.

Option C) SELECT Persons.FirstName - This option is incorrect. Although it specifies the desired column 'FirstName', it is missing the keyword FROM, which is necessary to indicate the table 'Persons' from which to retrieve the column.

Option D) SELECT * FROM Persons - This option is incorrect. The asterisk (*) symbol is used to select all columns from a table. It does not specifically select only the 'FirstName' column.

The correct answer is A) SELECT FirstName FROM Persons. This option is correct because it uses the SELECT statement to specify the 'FirstName' column from the 'Persons' table.
