You can use a comma to ignore certain elements of the array that you do not need:
const [,,width,height] = sizeArr;
function test() {
const viewBox = '0 0 24 24'
const sizeArr = viewBox.split(' ')
const [,,width,height]=sizeArr;
console.log(width,height);
}
test();
If you need to keep the let
declarations at the top of the function for some reason, you can remove the const
from destructuring. Note that you will need a semicolon at the end of the preceding line due to automatic semicolon insertion.
[,,width,height] = sizeArr;
function test() {
let height;
let width;
const viewBox = '0 0 24 24';
const sizeArr = viewBox.split(' ');
[,,width,height]=sizeArr;
console.log(width,height);
}
test();

If you do need every value, declare a name for each one:
const [var1,var2,width,height] = sizeArr;
function test() {
const viewBox = '0 0 24 24'
const sizeArr = viewBox.split(' ')
const [var1,var2,width,height]=sizeArr;
console.log(var1,var2,width,height);
}
test();
