Disable ESLint for a Single Line
You can disable ESLint for a given line using a // eslint-disable-line comment. For example, the below code would
cause ESLint to complain because of the no-use-before-define rule if you remove the eslint-disable-line comment.
const answer = getAnswer(); // eslint-disable-line
function getAnswer() {
return 42;
}A eslint-disable-line comment disables all ESLint rules for a given line.
That is dangerous, because you may unintentionally hide linter errors. For example,
the below line violates both the no-use-before-define rule and the no-undef rule, because undefinedVar is never declared.
const answer = getAnswer(undefinedVar); // eslint-disable-line
function getAnswer() {
return 42;
}If you want to disable just the no-use-before-define rule and leave all other
ESLint rules, you should use // eslint-disable-line no-use-before-undefined.
After // eslint-disable-line, you can list out the rules you want to disable,
separated by spaces.
const answer = getAnswer(undefinedVar); // eslint-disable-line no-use-before-define
function getAnswer() {
return 42;
}Disable the Next Line
Sometimes // eslint-disable-line can make a single line too long. You can use
eslint-disable-next-line instead:
// eslint-disable-next-line no-use-before-define
const answer = getAnswer(undefinedVar);
function getAnswer() {
return 42;
}
