Create a function that takes a string and replaces every nth instance of oldChar with newchar. Your function will have four parameters: • str - The original input text to be processed. • nth - The nth instance to be replaced. • oldChar - The character being replaced. • newChar - The character replacing oldChar. In other words, if str is "abababa", nth is 3, oldChar is "a" and newChar is "Z", you would replace the 3rd insrtance of "a" with "Z", returning "ababZba". Examples replaceNth ("A glittering gem is not enough.", 0, "o", "-") → "A glittering gem is not enough." replaceNth ("Vader said: No, I am your father!", 2, "a", "o") "Vader soid: No, I am your fother!" replaceNth ("Writing a list of random sentences is harder than I initially though "Writing a list of random sentences 3s harder than I in3tially thought 3t wol Notes • If nth is 0, negative or larger than instances of oldChar, return the original string. • Tests are case sensitive.

Answer the qust in the Java Script and use the opps concepts while answering the questions

Create a function that takes a string and replaces every nth instance of oldChar with
newchar. Your function will have four parameters:
• str - The original input text to be processed.
• nth - The nth instance to be replaced.
• oldChar - The character being replaced.
• newChar - The character replacing oldChar
In other words, if str is "abababa", nth is 3, oldChar is "a" and newChar is "Z", you would
replace the 3rd insrtance of "a" with "Z", returning "ababZba".
Examples
replaceNth ("A glittering gem is not enough.", 0, "o", "-")
→ "A glittering gem is not enough."
replaceNth ("Vader said: No, I am your father!", 2, "a", "o")
"Vader soid: No, I am your fother!"
replaceNth ("Writing a list of random sentences is harder than I initially though
"Writing a list of random sentences 3s harder than I in3tially thought 3t wol

Notes
• If nth is 0, negative or larger than instances of oldChar, return the original string.
• Tests are case sensitive.
