# 4 Ways to Combine Strings in JavaScript

1. Template Strings. Problem of Missing space in String concatenation. Resolved with Template Strings.
2. join() Customize Separator.
3. concat() Combining String with Array.
4. Plus Operator (+)

You can merge two or more JavaScript strings into one. The process of merging strings is called JavaScript string concatenation. To concatenate strings without relying on any built-in functions, you can use the + operator.

In formal language theory and computer programming, string concatenation is the operation of joining character strings end-to-end. For example, the concatenation of “snow” and “ball” is “snowball”.

The big difference between a template literal and a normal string is substitutions. The substitutions allow you to embed variables and expressions in a string. The JavaScript engine will automatically replace these variables and expressions with their values. This feature is known as string interpolation.

What is the correct way to concatenate a string variable (username) with a string (is online)?…

• username + ” is online”
• ” username” + ” is online.
• username + is online.

Concatenation is the process of appending one string to the end of another string. You concatenate strings by using the + operator. For string literals and string constants, concatenation occurs at compile time; no run-time concatenation occurs. For string variables, concatenation occurs only at run time.

Jinja also provides the ~ operator, which will ensure all values are converted to string first. My bad, in trying to simplify it, I went too far, actually stuffs is a record of all kinds of info, I just want the id in it. Thinking about it, stuffs is probably a dictionary, but you get the gist.

Jinja2 functions (macros, super, self.BLOCKNAME) always return template data that is marked as safe. String literals in templates with automatic escaping are considered unsafe because native Python strings (str, unicode, basestring) are not markupsafe.Markup strings with an __html__ attribute.

The same + operator you use for adding two numbers can be used to concatenate two strings. You can also use +=, where a += b is a shorthand for a = a + b. If the left hand side of the + operator is a string, JavaScript will coerce the right hand side to a string. That means it is safe to concatenate objects, numbers, null, and undefined.

Thinking about it, stuffs is probably a dictionary, but you get the gist. Yes I found the join filter, and was going to approach it like this: But the append doesn’t work without importing the extensions to do it, and reading that documentation gave me a headache.
