Add a character to the beginning and end of a string

Question

I am using a platform which uses a JavaScript-like syntax and allows to convert my values using regex.

I need to add a single quote at the beginning and at the end of a string, the string will always have 9 characters.

I.e.:

123456789 should be converted to '123456789'

What expression should I use?

Answer 1

You don't need a regular expression.

str = "123456789";  str = "'" + str + "'"; 

Answer 2

Although this question was asked a little early, newly defined backticks standard called Template Literals from ES6 provides new possibility to solve this question with a simpler syntax:

const str = '123456789'; const wrapped = `'${str}'`;
