In this case, defining the function is a technique that can be reusable in JavaScript code.
Hence, the correct answer is option “A”.
Explanation of Solution
Defining a function:
It is a technique which is used to perform the particular task when the function is called by user using its name. The function can be used multiple times by calling the function in JavaScript. So, the defined function can be reused in JavaScript code.
Explanation for incorrect options:
Create a script block:
In this option, creating a script is a block of code with “<script>” element. This block is used to write the set of code and the block is cannot be reused by the user.
Hence, the option “B” is wrong.
Define an “if” statement:
In this option, “if” statement is a conditional statement which is used to check the value of variable with its appropriate condition. If the condition returns true, then it displays the “true” block, otherwise it executes “false” block. So, it cannot be reused by user.
Hence, the option “C” is wrong.
Use an onclick event handler:
“Onclick” is an event handler which is processed when the user clicks on the event. It is a predefined technique and used for “click” event.
Hence, the option “D” is wrong.
