I'm new to JavaScript coming from Python background. In Python parameters can be passed as key and value as such:
def printinfo( name, age = 35 ):
print "Name: ", name
print "Age ", age
return;
Then the function could be called as such:
printinfo( age=50, name="miki" )
printinfo( name="miki" )
Can such parameters be passing in JavaScript functions?
I want to be able to pass one or more parameter. For example a JavaScript function as such:
function plotChart(data, xlabel, ylabel, chart_type="l"){
...
}
I want to be able to pass only data and chart type and labels are optional such as :
plotChart(data, chart_type="pie")
Is this possible with JavaScript?
A good way to do this would be to use an object for all of the arguments. Something like:
function plotChart(options) {
// Set defaults
options.chart_type = options.chart_type || '1';
// Check if each required option is set
// Whatever is used by the data
}
Then when the function is called:
plotChart({
data: 'some data',
xlabel: 'some xlabel',
ylabel: 'some ylabel',
chart_type: '5' // This is optional
});
