javasript array sort code example

Example 1: sort javascript array

var points = [40, 100, 1, 5, 25, 10];
points.sort((a,b) => a-b)

Example 2: sort function in react js

this.state.data.sort((a, b) => a.timeM > b.timeM ? 1:-1).map(
    (item, i) => <div key={i}> {item.matchID} {item.timeM} {item.description}</div>
)

Example 3: array sort js

arr = ['width', 'score', done', 'neither' ]
arr.sort() // results to ["done", "neither", "score", "width"]

arr.sort((a,b) => a.localeCompare(b)) 
// if a-b (based on their unicode values) produces a negative value, 
// a comes before b, the reverse if positive, and as is if zero

//When you sort an array with .sort(), it assumes that you are sorting strings
//. When sorting numbers, the default behavior will not sort them properly.
arr = [21, 7, 5.6, 102, 79]
arr.sort((a, b) => a - b) // results to [5.6, 7, 21, 79, 102]
// b - a will give you the reverse order of the sorted items 

//this explnation in not mine

Example 4: javascript sort

homes.sort((a, b) => parseFloat(a.price) - parseFloat(b.price));

Example 5: jvascript sort aray

var fruits = ["Banana", "Orange", "Apple", "Mango"];

fruits.sort();        // Sorts the elements of fruits
