There are multiple ways to remove duplicates from an array. The simplest approach (in my opinion) is to use theSetobject which lets you storeunique valuesof any type. In other words,Setwill automatically remove duplicates for us. constnames=['John','Paul','George','Ringo','John'];letuniq...
Given input arraynums=[1,1,2], Your function should return length =2, with the first two elements ofnumsbeing1and2respectively. It doesn't matter what you leave beyond the new length. https://leetcode.com/problems/remove-duplicates-from-sorted-array/ ...

operator before new Set()), we pass values and Set automatically removes the duplicates. Then we convert it to an array by wrapping it into square brackets [].This method works with anything that’s not an object: numbers, strings, booleans, symbols.Written...
“store unique values” → Sets don’t contain duplicates “without any particular order”, we should stick to lists if we care about ordering In practice, and within the lense of ES6 JavaScript (of which Sets are a part of): TheSetobject lets you store unique values of any type, whether...
