is-prop

Functional way to check if a property in an object equals something.

Basically return object[property] == value, but with functions.

npm install --save is-prop

Example

is-prop is useful when you want to test for equality in an object that's being passed to a function. It could for instance be used for filtering:

var isProp = require("./");
 
var data = [{
    name: "Jane",
    type: "patrician"
}, {
    name: "Bob",
    type: "plebeian"
}, {
    name: "Mauve",
    type: "patrician"
}];
 
var patricians = data.filter(isProp("type", "patrician"));
 
console.log(patricians);
/*
[
    { name: 'Jane', type: 'patrician' },
    { name: 'Mauve', type: 'patrician' }
]
*/
