Mi código Javascript no muestra el bit createElement("li") de mi programa. He intentado depurarlo, pero parece que hay algo que todavía me falta. Este es mi código.

 var state = { balance : 32, income: 0, expense: 220, transactions :[ {name:'Salary', amount: 5000, type: 'income'}, {name:'Groceries', amount: 30, type: 'expense'}, {name:'Buy Guitar', amount: 300, type: 'expense'} ] } var balanceEl = document.querySelector('#balance'); var incomeEl = document.querySelector('#income'); var expenseEl = document.querySelector('#expense'); var transactionsEl = document.querySelector('#transactions'); function init() { balanceEl.innerHTML = `$${state.balance}`; incomeEl.innerHTML = `$${state.income}`; expenseEl.innerHTML = `$${state.expense}`; var transactionsEl; for (var i = 0; i < state.transactions.length; i++) { transactionsEl = document.createElement("li"); transactionsEl.append(state.transactions[i].name); transactionsEl.appendChild(transactionsEl); } } init();
