}how to make an array in javascript
var names = ["Sanjith", "Pranav", "Aadya", "Saharsh"]js arrays
// Making an array:
const colors = ["red", "orange", "yellow"];
// Arrays are indexed like strings:
colors[0]; // "red"
// They have a length:
colors.length; //3
// Important array methods:
//push(value) - adds value to the END of an array
//pop() - removes and returns last value in array
//unshift(val) - adds value to START of an array
//shift() - removes and returns first element in an arrayjs arrays
// A javascript array is a list of elements in one variable.
//make an array like this:
var array = ["Nothing", "Something", 510, "anything"]
//You can log how many elements are in the array:
console.log(array.length);
// You can log a ["With your text and numbers in here"]:
console.log(array)
//you can also loop through an array like this:
for (var i = 0; i < array.length; i++) {
console.log(array[i]);
}
// "pop" will remove the last element from the array
var poppedarray = array.pop()
// Will output: ["Nothing", "Something", 510].
var pushedarray = array.push("anything");
// Now back to the original!
// now get the position of an element and their name:
fruits.forEach(function(item, index, array) {
console.log(item, index);
});
// Nothing 0
// Something 1
// 510 2
// Anything 3Copyright © 2021 Codeinu
