The analyzer has detected a suspicious method call, the return value of which is ignored. Calling some methods without using their return values is pointless.
The example:
/**

function escape(input) {
input.replaceAll(";", "\\;")
input.replaceAll(",", "\\,")

/**
* @param {string} input
* @returns {string}

return input
