对象文字字符串转义数学符号编号

Question

I have this string const myVar = '1-2' I want to do spacing and make the variable to become '1 - 2' .

I tried this ${myVar.split("-")[0] - myVar.split("-")[1]} , and the output I got is -1, because the - sign is being treated as math operator. Any help?

Answer 1

You could use .replace(). Just assign this to a new variable, so

const myVar = '1-2';
let newVar = myVar.replace("-", " - ");

newVar will be the result of myVar with spacing on each side of the hyphen.
