var str = tea;

I would like to make it as below

var quote_str = 'tea;'

Is there anyone can help me? Thanks in advance!

Edit:

I have tried the following code,however, it's not correct.

var quote_str =  'str';

I think that you want the semicolon outside the string literal:

var quote_str = 'tea';

If you mean that you want apostrophe characters inside the string also, you can use \' to put an apostrophe in a string delimited by apostrophes:

var quote_str = '\'tea\'';

You can also use quotation marks to delimit the string. Then you don't have to escape the apostrophes, but you have to escape the quotation marks:

var quote_str = "'tea'";

If you already have a string, and want to add apostrophes around it, you concatenate strings:

var quote_str =  "'" + str + "'";

Escape each single quote with a back-slash:

var quote_str = '\'tea;\''

…or wrap the string in quotes of a different kind (i.e. double quotes), but be sure to escape the inner double quotes as to not unintentionally close the string:

var quote_str = "'tea;'"

late update: now we have template literals, so the whole thing becomes a breeze:

var quote_str = `'tea;'`

You can escape characters in Javascript with the \. If that's your issue

We can use the backslash () escape character to prevent JavaScript from interpreting a quote as the end of the string.

The syntax of \' will always be a single quote, and the syntax of \" will always be a double quote, without any fear of breaking the string.

Using this method, we can use apostrophes in strings built with ".

'We\'re safely using an apostrophe in single quotes.' We can also use quotation marks in strings built with ".

"Then he said, \"Hello, World!\"";

In JavaScript, Strings are values made up of text and can contain letters, numbers, symbols, punctuation, and even emojis!

Single and Double Quotes in JavaScript Strings

Strings in JavaScript are contained within a pair of either single quotation marks '' or double quotation marks "". Both quotes represent Strings but be sure to choose one and STICK WITH IT. If you start with a single quote, you need to end with a single quote. There are pros and cons to using both IE single quotes tend to make it easier to write HTML within Javascript as you don’t have to escape the line with a double quote.

Enclosing Quotation Marks

Let’s say you’re trying to use quotation marks inside a string. You’ll need to use opposite quotation marks inside and outside of JavaScript single or double quotes. That means strings containing single quotes need to use double quotes and strings containing double quotes need to use single quotes.

Alternatively, you can use a backslash \ to escape the quotation marks. This lets JavaScript know in advance that you want to use a special character.

Here’s what that looks like reusing the examples above:

String Methods and Properties

Strings have their own built-in variables and functions, also known as properties and methods. Here are some of the most common ones.

String Length

A string’s length property keeps track of how many characters it has.

toLowerCase Method

A string’s toLowerCase method in JavaScript returns a copy of the string with its letters converted to lowercase. Numbers, symbols, and other characters are not affected.

toUpperCase Method

A string’s toUpperCase method returns a copy of the string with its letters converted to capitals. Numbers, symbols, and other characters are not affected.

trim Method

A string’s trim method returns a copy of the string with beginning and ending whitespace characters removed.
