Is there a way to prevent Javascript from recognizing the escape ( \ ) character?

Question

qAnswersR[12456] = [];
    qAnswersR[12456].push("[math]m: \frac{(x+20)^{2}}{256}+\frac{(y-15)^{2}}{81}=1[/math]");

To store the value in a variable, I tried logging the array like this:

console.log(qAnswersR[12456]);

The result displayed was:

[math]m: rac{(x+20)^{2}}{256}+rac{(y-15)^{2}}{81}=1[/math],[math]m: 81(x+20)^{2}+256(y-15)^{2}=20736[/math]

However, the escape tag "\" disappeared. How can I retain it?

Answer 1

Answer №1

One way to format strings is by using tagged template literals

const str = (s => s.raw)`[math]k: \frac{(x+20)^{2}}{256}+\frac{(y-15)^{2}}{81}=1[/math]`[0]

In this example, the arrow function acts as a tag and accesses the original content through s.raw

Answer 3

What should I do if the escape tag "\" disappears when I need it to stay?

To keep the backslash, you must double it up by using \\ instead of just \:

"[math]k: \\frac{(x+20)^{2}}{256}+\\frac{(y-15)^{2}}{81}=1[/math]"
          ^                       ^
