Question

What command can be used to omit commas when listing an array and join the words or items together?

Answer 1

To omit commas when listing an array and join the items together, you use the join method in programming languages such as JavaScript's .join('') or Python's ''.join(array), where you specify an empty string as the separator.

Step-by-step explanation:

To omit commas when listing an array and join the words or items together in a programming context, you can use a join method or function. This is common in many programming languages. For example, in JavaScript, you can use the .join('') method, specifying an empty string as the separator. In Python, you would also use the join method on a string to concatenate the items of a list.

Here is how you might do it in JavaScript:

var array = ['apple', 'banana', 'cherry'];
var joinedString = array.join(''); // 'applebananacherry'

And in Python:

array = ['apple', 'banana', 'cherry']
joined_string = ''.join(array) # 'applebananacherry'

The concept is the same across different languages; you are converting the array into a single string without any separator between the items.
