Array Methods:

For this page, all functions use the following [array], which has been declared globally:

membersDogsDAmour = ["Tyla", "Bam Bam", "Jo Dog", "Steve James"];

1. Manipulating [arrays]

array.push(item1, item2, ..., itemX);

Inserts value at end of [array]. Alters original [array]

Try Me

array.pop();

Removes value at end of [array]. Alters original [array] and returns a new [array]

Try Me

array.unshift(item1, item2, ..., itemX);

Inserts value at start of [array]. Alters original [array]

Try Me

array.shift();

Removes value at start of [array]. Alters original [array] and returns a new [array]

Try Me

array.fill(value, (start), (end));

Replaces value according to # indices. If no second #, fills to the end of [array]

Try Me

array.slice((start / -start), (end / -end));

Removes value according to # indices. If no second #, fills to the end of [array]. Does not change original [array]

Try Me

array.splice(index / -index, (howmany), (item1, ....., itemX));

Adds and/or removes value according to # indices. If no second #, fills to the end of [array]. Alters original [array]

Try Me

array.reverse();

Reverses original [array]

Try Me

array.sort((compareFunction));

Sorts original [array] (either alphabetically or numerically)

Try Me

array.concat(array2, array3, ..., arrayX);

Concatenates two [arrays]. Does not change original

Try Me

array.copyWithin(target, (start), (end));

Copies from within an [array]. Changes original

Try Me

Array.prototype.name=value;

Allows you to add new properties and methods to the Array() object
