How to choose the template string and the normal string of js?

if I usually use it at work, if a string needs to be calculated and concatenated by variables, then I will choose the template string, and I will still use the normal string at other times.
for example:

// 
var a = 1;
var b = 2;
var c = `Result is: ${a + b}.`;

// 
var d = "word";

my question is:
1. Since string templates are also used to represent strings, is it good to use template strings for all string definitions in future work?
2. How does it perform compared to common strings? (because I thought it would parse the variables inside)

is there any information you can recommend for reference?

string template is a feature of es6 and has compatibility issues in use.

if you already use es6 in your work, please feel free to use it. Otherwise, please be careful.

I think it's better to use a string template if you concatenate a variable in a string. In other cases, use single or double quotation marks.

performance, you don't need to think about it, you can't feel it.
