Most of my coding has been in ruby, but recently I have been working more with javascript. With that, working with arrays are slightly different in order to achieve the same goal.
Push:
- In order to push an item into an array, I like dot notation. Example: `let arr = [1, 2, 3, 4, 5]
arr.push(‘6’)`
Sort:
- When it comes to sorting in Ruby, ‘.sort’ will already order things from least to most. In Javascript, you need to specify. Example: ``` let arr = [2, 3, 1, 5, 4]
arr.sort((a, b) => a - b)
//arr now = [1, 2, 3, 4, 5]
Navigation:
- If you want to reach the last item in an array in Ruby, you can write array[-1]. However, Javascript does not work the same.
Example
let arr = [1, 2, 3, 4, 5]
arr[arr.length -1] //this will return 5
```
