javascript get from array code example

Example 1: javascript array

//create an array like so:
var colors = ["red","blue","green"];

//you can loop through an array like this:
for (var i = 0; i < colors.length; i++) {
    console.log(colors[i]);
}

Example 2: return array javascript

function func() {
  return [5, "string", {a: 7}];
}

Example 3: 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 array

Example 4: javascript get array value

var array = []
array[0] = "hi"
array[1] = "dude"
var done = false
while (done == false){
var valueToFind = "hi";
  var rounds = array.length;
  if (rounds < 0){
  return false
  }
  if (array[rounds] == valueToFind){
  done = true
    return rounds
  }
  rounds = rounds - 1
}
