I must retrieve information from a JSON object stored within my components.ts file

Currently, I'm in the process of retrieving information from a JSON object that is stored within my component.ts file.

Object_name=[
    {"name": "value_1","prop":["data_1","data_2","data_3"]},
    {"name": "value_2","prop":["data_1","data_2","data_3"]},
    {"name": "value_3","prop":["data_1","data_2","data_3"]}
];

My objective is to extract `object_name` and then verify if it contains `'value_1'`. If it does, I aim to retrieve the data under the "prop" key either into a variable or display it in the console. As I am relatively new to Angular, I would greatly appreciate it if you could provide your explanation with an example for better understanding.

Answer №1

Utilize the filter operator in your Object_name array

const filteredData = Object_name.filter(obj => obj.name === 'value_1');
filteredData.forEach(obj => console.log(obj.prop));

Answer №2

loop through the Object_name array and check if the name matches "value_1", then log the corresponding property
for (var index = 0; index < this.Object_name.length; index++) {
    if(this.Object_name[index].name == "value_1") {
      console.log(this.Object_name[index].prop)
    }
}

Answer №3

One way to iterate over an object is by using a for-in loop

for (const property in this.Object_name) {
    if (this.Object_name[property].name === 'value_1' ){      
       console.log(this.Object_name[property].prop);
    }   
}
