As a newcomer to programming, I have encountered similar questions before and attempted to apply the solutions without success.
Consider the following array:
var myArray = [24.203, 12*45, 000-1, 4567+00];
I aim to remove all non-integers from this array, resulting in the following:
var myArray = [24203, 1245, 0001, 456700];
I understand the use of the .replace method but struggle to implement it effectively. Here are four attempts I made:
function stripNonIntegers(arr) {
var x;
this.myArray = myArray;
for(x = 0; x < 10; x++) {
myArray[x] = myArray[x].replace(/\D/g, '');
} }
stripNonIntegers(myArray);
Unfortunately, this leads to an error stating that myArray is undefined.
var x;(myArray); { //I don't like the semicolons but I get an error if I omit them
for(x = 0; x < 10; x++)
{myArray[x] = myArray[x].replace(/\D/g, '');
} }
This attempt results in an error indicating that x is undefined.
stripNonIntegers= function(arr) {
for (x =0; x<this.length; x++)
myArray.replace(/\D/g,'');};
stripNonIntegers(myArray);
The output here is undefined.
var stripNonIntegers= myArray[x]; {
for (x=0; x<myArray.length; x++) {
stripNonIntegers = myArray.replace(/[^\d]/g, '');
} }
In this case, it also gives an error mentioning that x is undefined. This post provides guidance on using the .replace method with a regex /D to eliminate non-numeric characters from a string, but I struggle to adapt it to an array. Therefore, I attempted to incorporate a 'for' loop to treat each element as individual strings. Despite my efforts, I cannot pinpoint the mistake. I'm feeling quite lost.
Would greatly appreciate any insights or tips. Thank you!
