get one item from an array of name,value JSON

Question

I have this array:

var arr = [];
arr.push({name:\"k1\", value:\"abc\"});
arr.push({name:\"k2\", value:\"hi\"});
arr.push({name:\"k3\", value:\"oa\"});
         


        

Answer 1

The easiest approach which I have used is

var found = arr.find(function(element) {
         return element.name === "k1";
 });

//If you print the found :
console.log(found);
=> Object { name: "k1", value: "abc" }

//If you need the value
console.log(found.value)
=> "abc"

The similar approach can be used to find the values from the JSON Array based on any input data from the JSON.
