How to use .join() with push and replace together?
The array.push() function is used to push one or more values in an array. This function changes the length of an array by the number of elements added to the array. The syntax of the function is as follows:
arr.push(element1[, ...[, elementN]])
Arguments: This function can contain as many numbers of arguments as the number of elements to be inserted into the array.
Return value: This function returns the new array with new values after inserting the arguments into the array.
array.splice(start_index, delete_count, value1, value2, value3, ...)
Note: Splice() method deletes zero or more elements of an array starting with the start_index element and replaces those elements with zero or more elements specified in the argument list.
Example: Below is the example to illustrate the use of .join() method with push() method and splice() method together:
