[SOLVED] What wrong

Question

const fahTemp = eval(`(${secondInputValue} * 5/9) + 32`)

What wrong with this line of code. It's says unexpected token '*' when i try in react

Answer 1

I think that the problem comes from the type of secondInputValue, may you give its assignation code ?

Answer 2

VCoder i assigned it a value

Answer 3

Yes but how ? please, tell me the result of this line : console.log(typeof secondInputValue); //this line must come just before the assignation of celTemp

Answer 4

Yeah my bad. It's not assigned a value, because the first time page reload input field (secondInputValue) is empty

Answer 5

Already solved it
This is how i solved it:
const fahTemp = secondInputValue && eval(`(${secondInputValue} * 9/5) + 32`).toString()

Thanks fo help me figure out where is the problem

Answer 6
