You can turn off a line of code in eslint by adding this code to the line before:

// eslint-disable-next-line no-use-before-define
let a = 6;

or in the same line:

let b = 8; // eslint-disable-line no-use-before-define

or multi line:

/*eslint-disable */

let b = 6;
var a = 3;

/*eslint-enable */
