Array.from

eg:

getCheckArr(){
        const arr = [1,1,'true','true',true,true,15,15,false,false, undefined,undefined, null,null, NaN, NaN,'NaN', 0, 0, 'a', 'a',{},{}];
        // console.log('newSet',new Set(arr))
        const arr1=Array.from(new Set(arr))
        // console.log('arr1',arr1)
        const arr2=[...new Set(arr)]
        // console.log('arr2',arr2)
      }
