I have an array of JSON objects
array = [{name: "will", age: "18"}
{name: "Elliott", age: "21"}
]
Is there a way to get the "age" for any given "name" (as you would do with a SQL statement when querying a database?

Yes.
let array = [
{ name: "will", age: "18"},
{ name: "john", age: "18"},
{ name: "elliott", age: "21"}
]
array.filter((e) => { return e.name === 'john' })
Result
[ { name: 'john', age: '18' } ]

To extend this, is there a way of editing the "name" and "age" of those indexes in the array without removing the entire object and adding a new one?
Udlei Nati
let queryName = 'will';
array.forEach((obj) => {
if (obj.name === queryName) {
console.log(obj.name, obj.age); // will 18
}
});
