How can I use a variable substitution in this javascript code

Question

How can I use the name variable in this function?

function filter(name, value) {
    return data.filter(d => d.name == value);
}

I got just an Uncaught ReferenceError: d is not defined

In my data obj is no key name. I try to set the key (eg. vmax which exists) with the name variable. Is it possible to substitute the d. ? — exotec, Jul 30 '21 at 11:59
If you mean you want to use `name` as a way to access the property then you just use `[]` notation, eg `d=> d[name] == value`. — Patrick Evans, Jul 30 '21 at 12:00

You can access the property of an object with the syntax object[property]. So this is the solution to your case:

function filter(name, value) {
   return data.filter(d => d[name] == value);
}
