How to use the putout.isMemberExpression function in putout

function isThis(init, name) {
    if (!isMemberExpression(init))
        return;
    
    const {
        object,
        property,
    } = init;
    
    return isThisExpression(object) && isIdentifier(property, {name});
}

function isInitState(path) {
    const {node} = path;
    const {
        left,
        right,
    } = node;
    
    if (!isMemberExpression(left))
        return false;
    
    if (!isThisState(left))
        return false;
    
    if (!isObjectExpression(right))
        return false;
    
    return true;
}

CallExpression(chunk) {
            if (!isMemberExpression(chunk.callee))
                return;
            
            const {property} = chunk.callee;
            
            if (property.name !== 'get')
                return;
            
            push(chunk);
        },
    });
