Day 13: Learning JavaScript Arrays & For Loops 🚀

Today i learned Javascript arrays and for loops.

1.Arrays

An Array is used to multiple values in single variable.

let laptops = ["Hp","Dell","Msi","Lenovo"];

console.log(laptops);

Each value in an array has an index.The index starts from 0.

console.log(laptops[0]);
console.log(laptops[1]);

2.For Loop

I also learned how to use a for loop to repeat a block of code.

for(let i=1;i<=5;i++){
console.log(i);
}

This prints numbers from 1 to 5.

3.Using a for loop with an Array.

for loop can also be used to go through the values in an array.
`
let laptops = ["Hp", "Lenovo", "msi", "dell"];

for (let i = 0; i < fruits.length; i++) {
console.log(fruits[i]);
}`
