Perhaps too small question for it's own post...
So basically I'm looking for something like:
myarray[2, 3, 7] = 155, 34, true;
Is there some kind of line like this that works? Or what would be the shortest way to accomplish this, without changing all 3 manually?
If you're looking for something like destructuring assignment, that's not coming until ECMAScript 6, and won't look quite like that.
To do what you seem to want, you'll just need to assign separately.
myarray[2] = 155;
myarray[3] = 34;
myarray[7] = true;
Or create a function that handles it for you.
function assign(obj, props, vals) {
for (var i = 0; i < props.length; i++) {
obj[props[i]] = vals[i];
}
}
And call it like this:
assign(myarray, [2,3,7], [155,34,true]);
You could also opt to use the splice method like so:
var myArray = [2, 3, 7];
var otherArray = [155, 34, true];
function arrayChanger(firstArray, secondArray){
var orgLength = firstArray.length;
for(i = 0; i < orgLength; i++){
myArray.splice(i, 1, secondArray[i]);
}
return myArray;
};
arrayChanger(myArray, otherArray);
Here's a JSFiddle that shows this solution in action.
Use destructing to solve your problem
[myarray[2], myarray[3], myarray[7]] = [155, 34, true];
Solution Explanation
const myarray = [1,2,3,4,5,6,7,8];
[myarray[2], myarray[3], myarray[7]] = [155, 34, true];
console.log(myarray) // [1, 2, 155, 34, 5, 6, 7, true]
