What is the best way to intercept a JavaScript function, stop it from running within an if statement, and then allow the function to

    const options = ['option1', 'option2', 'option3', 'option4']

    function selectOption(option) {
        console.log('Selected Option -> ' + option);
    }

    setInterval(() => {
        selectOption(options[Math.floor((Math.random() * options.length))]);
    }, 1000);



    const _selectOption = selectOption;
    selectOption = function(selection) {
        if (selection == 'option3') {
            //If the selected option is 'option3' I want to prevent it from being logged, without interrupting the function flow. Simply returning will stop the function.
            //Therefore it should not be displayed in the log
        }
        console.log('Connected Option -> ' + selection);
        _selectOption(selection);
    }

In this scenario, I aim to intercept the selectOption function, verify if the choice matches a specific condition and avoid logging it if it does, all while keeping the function running smoothly. Instead of halting it, like a simple return statement inside the interception would do.

Answer №1

One effective approach is to execute the function when the value is anything other than Curse, rather than solely focusing on what is considered curse.

const queries = ['bite', 'attack', 'curse', 'heal']

function sendQuery(query) {
    console.log('Sending Query -> ' + query);
}

setInterval(() => {
    sendQuery(queries[Math.floor((Math.random() * queries.length))]);
}, 1000);

const _sendQuery = sendQuery;
sendQuery = function(e) {

    if (e != 'curse') {
        console.log('Hooked Query -> ' + e);
        _sendQuery(e);
    }
    
}
