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' }
]
*/
