How do i access a property on the objects in an array and compare it?-CodePudding

So, I have a array with multiple objects with multiple properties:

let myArr = [{
id: 1,
x: 120,
y: 150,
}, {
id: 2,
x: 170,
y: 420,
}, {
id: 3,
x: 160,
y: 220,
}, {
id: 4,
x: 140,
y: 170,
}];

Now I want to see if the property of one of the objects in my array matches a variable. But I dont know how to do that! I want to check if the value of property "id" in one of my objects matches my variable. Something like this:

if(myArr[0].id == myVar){
//do something
}

but this for each object in my array

Try like this

let myArr = [{
id: 1,
x: 120,
y: 150,
}, {
id: 2,
x: 170,
y: 420,
}, {
id: 3,
x: 160,
y: 220,
}, {
id: 4,
x: 140,
y: 170,
}];

let myVar = 1;

const found = myArr.find(element => element.id === myVar);

console.log(found)
