What is the procedure for removing an object from an array in typescript?
"revenues":[
{
"drug_id":"20",
"quantity":10
},
{
"drug_id":"30",
"quantity":1
}]
I am looking to delete the drug_id from all objects. Can you provide guidance on how to accomplish this? Thank You!
Here is a solution you could consider:
this.revenues = this.revenues.map(r => ({quantity: r.quantity}));
If you are looking for a more versatile approach, you can try the following method:
removePropertiesFromRevenues(...props: string[]) {
this.revenues = this.revenues.map(r => {
const obj = {};
for (let prop in r) { if (!props.includes(prop)) { obj[prop] = r[prop]; } }
return obj;
});
}
To implement the Array.prototype.map method, follow this pattern:
results = input.map(item => ({property: item.property}));
By using Array.prototype.map, each element in the input array can be customized before being returned.
The map() function generates a new array by applying a specified operation to each element within the original array.
If, for instance, you wish to modify each property and create additional fields, consider the following approach:
results = input.map(item => ({property: item.property, doubledProperty: item.property * 2}));
everything seems to be functioning properly
for (let rev of revenues) {
delete rev.drug_id;
}
