Arrays and Objects on Loop.
More key elements of JavaScript are arrays, loops and objects. Arrays are like lists for JavaScript as you can store items, like food items, in them and add or remove items if need be. To output an entire list, you will have to loop through them.
Objects are variables that can store multiple bits of information relating to something. For example, a person can represented by an object as they will have information such as name, age, height, etc.
Below are examples of loops, arrays, objects, looping through arrays, objects with arrays, looping through objects with arrays.
JavaScript Code
//Example 1
function timesTable(number){
for(let i = 1; i < 13; i++){
let multiple = i * number;
console.log(`${i} x ${number} = ${multiple}`);
}
}
let number = 7;
timesTable(number);
