Function unique

Combines the values of one or more arrays, removing duplicates.

const eq = (a, b) => {
 return a.name === b.name
}
const v = Arrays.unique([ 
 [ {name:'jane'}, {name:'billy'}, {name:'thom'} ], 
 [ {name:'molly'}, {name:'jane'}, {name:'sally'}, {name:'thom'}] 
], eq);
// [ {name:'jane'}, {name:'billy'}, {name:'thom'}, {name:'molly'}, , {name:'sally'} ]
Copy

A single array can be provided as well:

const v = Arrays.unique([ 
 {name:'jane'}, {name:'billy'}, {name:'thom'}, {name:'billy'},
], eq);
// [ {name:'jane'}, {name:'billy'}, {name:'thom'} ]
Copy

See also:

• intersection: Get overlap between two arrays
• Iterables.additionalValues: Yield values from an iterable not present in the other
• containsDuplicateValues: Returns true if array contains duplicates

Combines the values of one or more arrays, removing duplicates.

Compares based on a string representation of object. Uses a Set to avoid unnecessary comparisons, perhaps faster than using a comparer function.

const str = (v) => JSON.stringify(v);
const v = Arrays.unique([ 
 [ {name:'jane'}, {name:'billy'}, {name:'thom'} ], 
 [ {name:'molly'}, {name:'jane'}, {name:'sally'}, {name:'thom'}] 
], str);
// [ {name:'jane'}, {name:'billy'}, {name:'thom'}, {name:'molly'}, , {name:'sally'} ]
Copy

const v = Arrays.unique([ 
 {name:'jane'}, {name:'billy'}, {name:'thom'}, {name:'billy'},
], eq);
// [ {name:'jane'}, {name:'billy'}, {name:'thom'} ]
Copy

By default uses JSON.toString() to compare values.
