CONCAT AND JOIN ARRAYS IN JAVASCRIPT

In programming, concatenation and join are both ways of combining elements, but they work differently and are used in specific contexts:

Concatenation: This refers to linking together strings or arrays in a sequential manner. For example, in many programming languages, using the + operator with strings will concatenate them. So "Hello " + "World" results in "Hello World".

Join: This method is often used to combine an array or list of elements into a single string, using a specified separator. For instance, in JavaScript, calling ["Hello", "World"].join(" ") would produce "Hello World", with a space inserted between each element.

In short, concatenation is directly linking elements, while join uses a separator to create a combined result from an array or list...#learnhtml5andcss3#codingchallenge #code #webdevelopment #codewithme #codewithharry#apnacollege #apnacollegestudent #frontenddevelopment#codewithharry #Trending
