JavaScript - 在一行中格式化多个变量输出

Question

I've searched as much as I can but can't seem to find what I'm looking for.

I'm trying to write a simple JS command that will output a formatted string that contains 3 variables that are evenly spaced.

For example, when I did this in C++ I used setw

Sample output would be like this:

var1 = "First"
var2 = "Second"
var3 = "Third"

[VARIABLE 1][VARIABLE 2][VARIABLE 3]
    First      Second      Third

Thanks in advance!

Answer 1

You can use String.prototype.padEnd() and String.prototype.padStart() and length of string to do that.

Code below:

var1 = "First";
var2 = "Second";
var3 = "Third";

//skip 3 whitespace each string
console.log(
   var1.padStart(3+var1.length)
   +var2.padStart(3+var2.length)
   +var3.padStart(3+var3.length));

Hope it makes your day.
