变量'value‘在赋值之前使用。开发者社区

function test() {
  let value: number;
  for (let i = 0; i < 10; i++) {
    value = i;
    console.log(value);
  return value;
test();

Variable 'value' is used before being assigned

function test() {
  let value: number;
  for (let i = 0; i < 100; i++) {
    // a() is very expensive and with some effects
    const result = a(i)
    if(i===99) {
      value = result
  return value;
}

function test() {
  let value!: number;
  for (let i = 0; i < 10; i++) {
    value = i;
    console.log(value);
  return value;
test();

function test() {
