This is part of the code; the function works correctly, however having trouble coding the comparison statement in order to display correct letters on screen

function play() {
    let index = Math.floor(Math.random()* words.length)
    console.log(words[index])
    for(let i = 0; i < words[index].length; i++){
        console.log(words[0][i])
        let div = document.createElement('div')
         div.innerHTML=' - '//words[0][i]
        document.querySelector('.hold-words').append(div)
//This is the section I know is incorrect looking for guidelines 
        if (words[index] === ' - '){
            words.innerHTML === ' - '
            wordSpace = '- '
            
        }
        words.push('- ')
        
        
    }const buttons = document.querySelectorAll('button')
    buttons.forEach(button => button.addEventListener('click', e => {
        console.log(e.target.innerHTML)
    }))
