JavaScript Format String

JavaScript Format String

The format string is composed of some operands and made to generate a real string by arguments. There are many programming language with the official format string method; for example, in C, it can use sscanf within %d, %s, %f, etc. to stand for the type from the auguments; similarly, in Python, it can use string.format within ${0}, ${1}, etc. to represent the order of the coming arguments.

Fortunately, in JavaScript, there is a method similar to those modern languages. However, the format string is a little different from the general string. The difference is using the graven accent instead of the quotation marks. The usage is like the following:

var a = 10;

var b = ‘hello world’;

var s = ` test ${a} ${b}`;

Now, you can use the string be composed of the arguments.
