How to get string between single quotes in javascript
I have a string that looks like this: "the word you need is 'hello' ". Show
What's the best way to put 'hello' (but without the quotes) into a javascript variable? I imagine that the way to do this is with regex (which I know very little about) ? Any help appreciated! asked Sep 11, 2012 at 9:54

Often while coding using javascript, you would have come across the use of 'single' or "double" quotes for strings and would have wondered, if there is any real difference between the two and if there is, is there an advantage of using one type of quote over the other? This article is going to answer just that! Read on! Table of Contents
Difference between the two quoting stylesBoth single (' ') and double (" ") quotes are used to represent a string in Javascript. Choosing a quoting style is up to you and there is no special semantics for one style over the other. Nevertheless, it is important to note that there is no type for a single character in javascript, everything is always a string!
Some of the other key points that both styles of quoting are as follows:
Choosing the right quoting styleWise selection of quoting can help you from escaping single (') or double(") quotes within a string. For example, if you wish to store a HTML snippet in a variable, you can use double quotes (") for HTML attribute values and use single quotes (') for enclosing the JavaScript string:
Quote within a quoteUsing quotations within a string gives rise to an error. for example,
There is no way for the browser to know which one is the closing quote. The interpreter sees the second quote in 'Javascript's as the ending quote - so the rest of the line becomes invalid. We can fix this by using the fact that javascript allows both single and double quotes to define a string. So in this case you can go for double-quotes.
An alternate method is to escape quote arks using a forward slash "\". You use a forward slash in front of the character you intend to escape. So the same message becomes:

Popular Quoting StyleCombing through a few popular JavaScript projects we can see a clear preference for single quotes over double-quotes.

Parting wordsTo sum it up, try to stick with one quoting style throughout. If you are confused about which one to pick, go with the widely-used single quotes. In ES6, you also have a third option to enclose strings - the `backtick`string. Can you use single quotes for strings in JavaScript?Both single (' ') and double (" ") quotes are used to represent a string in Javascript. Choosing a quoting style is up to you and there is no special semantics for one style over the other.
How do you handle a single quote in JavaScript?Using the Escape Character ( \ )
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.
Can you use single quotes for string?Single-quoted Strings: It is the easiest way to define a string. You can use it when you want the string to be exactly as it is written. All the escape sequences like \r or \n, will be output as specified instead of having any special meaning. Single-quote is usually faster in some cases.
How do you strip quotes in JavaScript?Use the String. replaceAll() method to remove all double quotes from a string, e.g. str. replaceAll('"', '') .
