I have multiple 'sort options' that id like to pass to make this function re-usable, but all passed strings result in undefined when being used to target the objects key. If I hard code the value - name - then it will sort properly. Thanks!
const sortNames = [
{ name: "Maddox", age: 69 },
{ name: "John", age: 69 },
{ name: "Alex", age: 69 },
{ name: "Mike", age: 69 },
];
const sortSomeStuff = (param) => {
const result = sortNames.sort((a, b) => {
const paramA = a.param.toLowerCase();
const paramB = a.param.toLowerCase();
if (paramA > paramB) {
return -1;
}
if (paramA < paramB) {
return 1;
}
return 0;
});
return result;
};
console.log(sortSomeStuff("name"));
To have a variable to map an object use [] like this. Also added sort directions.
const sortNames = [
{ name: "Maddox", age: 20 },
{ name: "John", age: 69 },
{ name: "Alex", age: 69 },
{ name: "Mike", age: 69 },
];
const sortSomeStuff = (param, dir="asc") => {
const result = sortNames.sort((a, b) => {
var paramA = a[param].toString().toLowerCase();
var paramB = b[param].toString().toLowerCase();
if(dir=="dsc"){
paramA = b[param].toString().toLowerCase();
paramB = a[param].toString().toLowerCase();
}
if (paramA < paramB) {
return -1;
}
if (paramA > paramB) {
return 1;
}
return 0;
});
return result;
};
console.log(sortSomeStuff("age","dsc"));
