Clumsy Crayfish
var list = ["apple","banana","orange"]
var index_of_apple = list.indexOf("apple") // 0// for dictionary case use findIndex
var imageList = [
{value: 100},
{value: 200},
{value: 300},
{value: 400},
{value: 500}
];
var index = imageList.findIndex(img => img.value === 200);// find index of array in javascript
const number = [1,6,2,8,1,0,4,2,7,5,4,1];
const index = number.findIndex(item => item === 8);
console.log(index)var valueAtIndex1 = myValues[1];
