how to get the index of element in array js

Comment

// If you want to find the index of item present in array then here is 
// a method call indexOf with this method you can find index of item

// EXAMPLE ----

// Tip : 1

// Use const to define a Array because you know javascript stores 
// refrence data types in heap // It's mean you can access the array 
// Dynamically

const names = ["Fahad","Shaikh","Your_Name"]

// It'll log the result in the console

console.log(names.indexOf("Your_name")); // And you guess right it'll 
// return ---> 2 because Your Name is present in names[2]

// And if you want to store the index in a variable you use syntax 
// given below

// Tip : 2

// use camel case to define variable names and don't be afraid to give
// big name to variable 

const indexOfYourName = list.indexOf("apple") // 0

// Enjoy Coding : )
