move an object to 0 position in array object typescript code example

Example 1: javascript move item in array to another index

function moveArrayItemToNewIndex(arr, old_index, new_index) {
    if (new_index >= arr.length) {
        var k = new_index - arr.length + 1;
        while (k--) {
            arr.push(undefined);
        }
    }
    arr.splice(new_index, 0, arr.splice(old_index, 1)[0]);
    return arr; 
};

//move index 1(b) to index 2(c)
console.log(moveArrayItemToNewIndex(["a","b","c","d"], 1, 2)); // returns ["a", "c", "b", "d"]

Example 2: move element to the top of list javascript

const data= [{code:"001",name:"Kirk-Patrick Brown"},{code:"002",name:"Sara Brown"},{code:"003",name:"Joe Frazer"}];

const firstItem = "003";
data.sort((x,y)=>{ return x.code === firstItem ? -1 : y.code === firstItem ? 1 : 0; });

console.log(data);
