I'm new to the world of JavaScript/TypeScript and I currently have an array filled with objects.
My goal is to convert the value into an integer. Right now, I am achieving this by using the following mapping method:
var k = [{key: "apples", value:"5"}, {key: "orange", value:"2"}];
var output = Object.entries(k).map(([key,value]) => ({key,value}));
console.log(output)The desired output would be:
[{key: "apples", value:5}, {key: "orange", value:2}]
Avoid using Object.entries() on your array, as you can directly utilize .map() on the k array. Deconstruct each object to extract its value property and then map it to a new object with the value converted to a numeric value using the unary plus operator (+value):
const k = [{key: "apples", value:"5"}, {key: "orange", value:"2"}];
const output = k.map(({value, ...rest}) => ({...rest, value: +value}));
console.log(output)If you prefer to modify the array in-place, iterate over the objects within it using a .forEach loop, and update the value by accessing it with dot notation like this:
const k = [{key: "apples", value:"5"}, {key: "orange", value:"2"}];
k.forEach(obj => {
obj.value = +obj.value; // Use `+` for string-to-number conversion
});
console.log(k)When the item id already exists, the quantity should be added to the incoming quantity. If the id does not exist, then insert the id and its quantity. Here is an example of what should be inserted into the table: if item_id=array(24,25); quantity=arra ...
