I am facing an issue with sorting arrays. I have a custom logic for displaying the array where each object has a 'code' column with values ('A', 'B', or 'C'). The requirement is to sort the records to display 'B' first, then 'A', and finally 'C'.
Link to my code is available on StackBlitz.
Below is the code snippet:
list.sort(function (el1, el2) {
if (el1.codeNumber > el2.codeNumber) {
return 1;
}
if (el1.codeNumber < el2.codeNumber) {
return -1;
}
return 0;
});
To streamline the code, consider using an object to arrange items based on a specific code.
const
list = [{ name: 'Bala', age: 21, code: 'A' }, { name: 'Bala', age: 22, code: 'A' }, { name: 'Bala', age: 23, code: 'C' }, { name: 'Bala', age: 24, code: 'A' }, { name: 'Bala', age: 25, code: 'B' }, { name: 'Bala', age: 26, code: 'B' }, { name: 'Bala', age: 27, code: 'B' }, { name: 'Bala', age: 28, code: 'A' }, { name: 'Bala', age: 29, code: 'B' }, { name: 'Bala', age: 30, code: 'C' }, { name: 'Bala', age: 31, code: 'C' }, { name: 'Bala', age: 31, code: 'C' }, { name: 'Bala', age: 28, code: 'A' }],
order = { B: 1, A: 2, C: 3 };
list.sort((a, b) => order[a.code] - order[b.code]);
console.log(list);.as-console-wrapper { max-height: 100% !important; top: 0; }Here is a piece of code that I have written: fetch(`${URL}${PATH}`) .then(res => { const d = res.json(); console.log("The data is: ", d); return d; }) When the code runs, it outputs The data is: Promise { <pending> ...
