How to remove substring and comma if exist on left or right side

Question

I have the following string:

"house,car,table"

I need to properly handle the comma removal, so much so that If I remove "car" the output should be:

"house,table"

If I remove "table" the output should be:

"house,car"

Answer 1

You can use the .split() in an array then .filter() out the target text after words .join() to create a string.

var str = "house,car,table";
str = str.split(',').filter(x => x !== 'car').join(',');

console.log(str)

Answer 2

You can use string#split, string#indexOf array#splice and arr#join

var str = "house,car,table";
var arr = str.split(',');

var index = arr.indexOf('car');
arr.splice(index, 1);

console.log(arr.join(','));
