Hey there! I'm working with a JavaScript array that looks a little something like this.
{x: red, y: 2}
{x: blue, y: 3}
{x: blue, y; 4}
{x: green, y: 5}
I'm wondering how to combine the duplicate values so that my array ends up looking like the code snippet below.
Is it possible to achieve this using a loop? I have a large amount of data that needs to be formatted in the same way.
{x: red, y: 2}
{x: blue, y: 7} #the two blue y variables have been added
{x: green, y: 5}
Here is a suggestion:
var newArr = [];
const data=[{x:"red",y:2},{x:"blue",y:3},{x:"blue",y:4},{x:"green",y:5}];
var uniqueX = []
data.forEach((element) => {
if (!newArr.includes(element.x)) {
uniqueX.push(element);
newArr.push(element.x);
} else {
uniqueX.forEach(item => item.y += item.x == element.x ? element.y : 0);
}
})
console.log(uniqueX);My query using odata looks like this: http://localhost:5000/odata/Levels?$filter=contains(Code, '+14') However, when the query reaches my controller, I notice that the filter object received is altered to be: {contains(Code, ' 14')} T ...
