The remove() method of p5.TypedDict in p5.js is used to remove the given key-value pair from the typed dictionary. A key-value pair is a set of two values that are mapped to each other. These values can be accessed by querying this dictionary using the key portion of the pair. A typed dictionary can store multiple key-value pairs that can be accessed using the methods of the dictionary.
Syntax:
remove( key )
Parameters: This method accepts a single parameter as shown above and discussed below:
- key: This is a string that denotes the key that has to be checked in the dictionary.
The example below illustrates the remove() method in p5.js:
Example:
function setup() {
createCanvas(550, 400);
textSize(16);
let tmpObj = {
"Statue of Unity" : "182 m" ,
"Spring Temple Buddha" : "128 m" ,
"Ushiku Daibutsu" : "100 m" ,
"Great Buddha of Thailand" : "92m"
};
// Create a new string dictionary
let stringDict =
createStringDict(tmpObj);
text( "New string dictionary created" , 20, 20);
// Checking the size of the dictionary
let currSize = stringDict.size();
text( "The current size of the " +
"dictionary is: " + currSize, 20, 40);
let existOne =
stringDict.hasKey( "Statue of Unity" );
text( "Dictionary has key " +
"'Statue of Unity': " +
existOne, 20, 80);
let existTwo =
stringDict.hasKey( "Spring Temple Buddha" );
text( "Dictionary has key " +
"'Spring Temple Buddha': " +
existTwo, 20, 100);
// Removing one key
stringDict.remove( "Spring Temple Buddha" );
text( "One key removed from the dictionary" ,
20, 140);
// Checking the size of the dictionary again
currSize = stringDict.size();
text( "The current size of the dictionary is: " +
currSize, 20, 160);
// Checking for the removed key
existTwo =
stringDict.hasKey( "Spring Temple Buddha" );
text( "Dictionary has key " +
"'Spring Temple Buddha': " +
existTwo, 20, 200);
// Checking the other keys
let existThree =
stringDict.hasKey( "Ushiku Daibutsu" );
text( "Dictionary has key " +
"'Ushiku Daibutsu': " +
existThree, 20, 220);
