Looking for a way to manipulate an array of objects
[ { url : "http:image.gif"}, { url : "http:image.gif"} , { url : "http:image.gif"}]
Need a function that can remove one object each time it is called until the array is empty.
Here's an example:
function Decrement(){
if the array is not empty
var lastKey = _.last (object);
var updatedObject = _.without ( object, lastkey);
return the last key of the new updatedObject
}
If you're looking to reduce the size of an array in JavaScript, one option is to utilize both the pop method and lodash's _.last function:
function decreaseSize(array) {
array.pop();
return _.last(array);
}
var nums = [1, 2, 3];
function decreaseSize(array) {
array.pop();
return _.last(array);
}
var result = decreaseSize(nums);
console.log(result, nums);<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.15.0/lodash.min.js"></script>Encountering an issue where a simple same-origin fetch("fetch.xml") call fails, resulting in a console error message Access to fetch at 'http://127.0.0.1:8000/fetch.xml' from origin 'null' has been blocked by CORS policy: Th ...
