If you want to filter an array based on a specific property value, you can use the Array.prototype.filter method in JavaScript.
var filteredArray = originalArray.filter(function(obj) {
return obj.property === value;
});
console.log(filteredArray);
# [ { property: value } ]
Another way to achieve this is by using a simple for loop:
var filteredArray = [];
for (var i = 0; i < originalArray.length; i++) {
if (originalArray[i].property === value) {
filteredArray.push(originalArray[i]);
}
}
console.log(filteredArray);
# [ { property: value } ]
let finalResult;
for (let index = 0; index < myArray.length; index += 1) {
if (myArray[index].b === 2) {
finalResult = myArray[index];
break;
}
}
console.log(finalResult);
Add a break statement to bring some variation.
