A challenge I am facing involves an array with multiple elements. My goal is to remove the last two digits from any element in the array that consists of 3 or 4 digits, while leaving elements with 1 or 2 digits unchanged.
var test =[ 2, 45,567, 3, 6754];
The desired output is :
[ 2, 45, 5, 3, 67];
I attempted a solution using:
test.forEach(function(element, index) { test[index] = element.slice(1, -2); });
However, this approach resulted in blanking out single-digit elements.
To get the integer value, you can divide the number by 100 and then round down if needed.
const
values = [2, 45, 567, 3, 6754],
updatedValues = data.map(val => val >= 100 ? Math.floor(val / 100) : val);
console.log(updatedValues);The solution you provided is ineffective because it attempts to slice values of type number.
Consider using the following code snippet instead:
test.forEach(function(element, index) {
test[index] = String(element).length > 2 ? +String(element).slice(0, -2) : test[index]
});
