Query:
I'm working on a JavaScript project and I have an array that looks like this: [6.7, 8, 7, 8.6]. I need to transform this array into an array of objects with named properties:
[{y: 6.7} , {y: 8}, {y: 7}, {y: 8.6}].Thank you in advance!
If you need a valid JSON object, you can use the following code snippet:
https://jsfiddle.net/6k3wnbs8/1/
var numbers = [6.7, 8, 7, 8.6];
for(var i in numbers) {
numbers[i] = {};
numbers[i]["value"] = numbers[i];
}
console.log(numbers);
If you want the output to be exactly as mentioned in the question [y: 6.7 , y: 8, y: 7, y: 8.6], you can use the following code:
var numbers = [6.7, 8, 7, 8.6];
for(var i in numbers) {
numbers[i] = "y: " + numbers[i]
}
console.log(numbers);
One way to create an array of objects is by using the map method.
[6.7, 8, 7, 8.6].map(function(num) { return {value: num} })
Here is the solution to your query mentioned in the comments:
var xValues = [1.1, 2.2]
var yValues = [3.3, 4.4]
var output = []
function objectCreator(property, values) {
for (var i = 0; i < values.length; i++) {
if (output[i] === undefined) {
output[i] = {};
}
output[i][property] = values[i];
}
}
objectCreator("x", xValues);
objectCreator("y", yValues);
console.log(JSON.stringify(output));
To achieve this task, you can utilize the Array method known as map. Below is an example illustrating this concept:
let numbers = [10.5, 15, 12.2, 18.6];
function formatNumber(num) {
return 'x: ' + num ;
};
let formattedNumbers = numbers.map(formatNumber);
console.log(formattedNumbers);
