Reference Error on line 7: i is not defined JavaScript

I am trying to create a for loop to iterate through an array called "synonyms"; then I want to push a greeting string with the format "Have a [synonym] day!" into a new "greetings" array.

I encounter the following error when executing my code: Reference Error on line 7: i is not defined

const synonyms = ['fantastic', 'wonderful', 'great'];
const greetings = [];

// 1.
// Loop through the synonyms array. Each time, push a string into the greetings array. 
// The string should have the format 'Have a [synonym] day!'
for (i = 0; i < synonyms.length; i++) {
  let newString = "Have a "+ synonyms[i] + " day!";
  greetings.push(newString);
}

I think the for loop is set up correctly. What's causing my error and any other suggestions to refactor would be greatly appreciated.

Your initialization step in the for loop is missing the let keyword when declaring the variable

const synonyms = ['fantastic', 'wonderful', 'great'];
const greetings = [];

// 1.
// Loop through the synonyms array. Each time, push a string into the greetings array. 
// The string should have the format 'Have a [synonym] day!'
for (let i = 0; i < synonyms.length; i++) {
  let newString = "Have a "+ synonyms[i] + " day!";
  greetings.push(newString);
}
