Javascript: While Loop to Solve Exponents Problem Getting Error When Power Equals 0

Question

I wrote javascript code to solve the following problem >>> Write a function exponentiate that accepts two arguments: base (number) power (number) Exponentiate should return the result of raising the base by the power. Assume the power argument will always be an integer greater than or equal to zero. Don't forget that any number raised to the 0th power is equal to 1! function exponentiate (base, power) { if (power === 0){ return result = 1 } // while loop let count = 0 let result = 1; while (count < power){ result *= base count += 1 } return result } exponentiate(3, 0) But I get the following error: ReferenceError: result is not defined What is wrong with my code?

Answer 1

You're accessing result before it is defined. so you should move them at the top of function Here you should return value directly instead of assignment if (power === 0){ return result = 1 } function exponentiate (base, power) { let count = 0 let result = 1; if (power === 0){ return 1 } // while loop while (count < power){ result *= base count += 1 } return result } console.log(exponentiate(3, 0)) Run code snippetExpand snippet Simplest is using ** exponent operator const exp = (b,e)=>{ return b**e } console.log(exp(3,0)) console.log(exp(3,1)) console.log(exp(2,10)) Run code snippetExpand snippet
