Lecture No 25 Advance JavaScript Learn Slice or Splice Urdu / Hindi

slice The term ‘slice’ literally means to cut something into pieces. It is used to cut out elements from an array. It does not affect the original array. Syntax array.slice(start, end) start denotes the index at which the array starts slicing. end denotes the index at which the array stops slicing. Return value The returned value of the slice method is an array of the values found between start and end excluding the value at end. If end is not specified, the length of the array would be used. Hence, all values from the start index would be returned. splice ‘Splice’, according to the dictionary, means to join things together. It is used to remove elements from an array or replace them. Syntax array.splice(start, deleteCount, newElem1, newElem2, ..., newElemN; start denotes the index from which the method will start its operation on the array. deleteCount denotes the number of values to be deleted from the start. If the value is 0, nothing will be deleted. newElem1 to newElemN denote the values that would be added after the start. Return value The returned value is the values that are affected,i.e., deleted. If deleteCount is 0, an empty array would be returned. #Reactjs #development #developer #vuejs #angularjs #learn #findindex #find #javascript #javascriptengineer #filter #map #foreach #reducere #every #some #alert #prompterchallenge #prompt #confirm #slice #splice Lecture No 7 : - How To Used Map Function in JavaScript.(React js, Node js, Vue js) |    • Lecture No 7 : - How To Used Map Func...   Lecture No 8 : - How To Used JavaScript forEach in JavaScript.(React js, Node js, Vue js) |    • Lecture No 8 : - How To Used JavaScri...   Lecture No 10 : - How To Used filter Function in JavaScript.(React js, Node js, Vue js) |   • Lecture No 10 : - How To Used filter ...   Lecture No 11 : - How To Used find Function in JavaScript.(React js, Node js, Vue js) |    • Lecture No 11 : - How To Used find Fu...   Lecture No 12 : - How To Used findIndex Function in JavaScript React js, Node js, Vue js |    • Lecture No 12  : -   How To Used find...   Lecture No 13 How To Used Reducer Function in JavaScript React js, Node js, Vue js |    • Lecture No 13   How To Used Reducer F...   Lecture No 14 How To Used some & every Function in JavaScript React js, Node js, Vue js |    • Lecture No 14 How To Used some & ever...   Lecture No 15 How to Swap Two variable in JavaScript without 3rd variable use |    • Lecture No 15 How to Swap Two variabl...   Lecture No 16 Advance Array Destructuring in JavaScript |    / @saqitechnical2526   Lecture No 17 Advance JavaScript Object Destructuring. |    • Lecture No 17 Advance JavaScript Obje...   Lecture No 18 How to used & Work Fat arrow Function |    • Lecture No 18 How to used & Work Fat ...
