Which function is used to schedule a function to be executed after a specified delay in JavaScript?OptionssetTimeout()setDelay()wait()setInterval()

Break Down the Problem

1. Identify the functions given in the options.
2. Understand the purpose of each function in JavaScript concerning scheduling execution after a delay.

Relevant Concepts

• setTimeout(): This function is specifically designed to execute a piece of code after a specified amount of time (in milliseconds).
• setDelay(): This is not a standard function in JavaScript.
• wait(): This is not a recognized method in JavaScript for scheduling delay.
• setInterval(): This function is used to repeatedly execute a piece of code at specified intervals, not just once after a delay.

Analysis and Detail

• setTimeout(): The correct function for scheduling a function to be executed once after a specified delay is setTimeout(), which takes two parameters: the function to execute and the delay in milliseconds as the second argument.
• The other functions (setDelay() and wait()) do not exist in JavaScript’s standard library.
• setInterval() executes a function repeatedly at intervals, rather than a one-time delay.

Verify and Summarize

Upon reviewing the definitions and purposes of each function, setTimeout() is the clear and correct choice for executing a function after a specified delay.

Final Answer

The correct function to schedule a execution after a specified delay in JavaScript is setTimeout().
