traverse.js

A cascading data traversal library

API Reference

.data([dataset])

• Loads the dataset into traverse. You should be assigning an array to this only.

Example:

t.data([1,2,3,4,5]);

.gt([int|string])

Evaluates the dataset for everything greater than the integer or string.

Example:

var dataset = t.data([1,2,3,4,5]).gt(3).result();
console.log(dataset);
//Returns [4,5];

.gte([int|string])

Evaluates the dataset for everything greater than or equal to the integer or string.

Example:

var dataset = t.data([1,2,3,4,5]).gte(3).result();
console.log(dataset);
//Returns [3, 4,5];

.lt([int|string])

Evaluates the dataset for everything less than to the integer or string.

Example:

var dataset = t.data([1,2,3,4,5]).lt(3).result();
console.log(dataset);
//Returns [1,2];

.lte([int])

Evaluates the dataset for everything less than or equal to the integer or string.

Example:

var dataset = t.data([1,2,3,4,5]).lte(3).result();
console.log(dataset);
//Returns [1,2,3];

.findByValue([int|string])

Evaluates the dataset to find everything equal to that value

Example:

var dataset = t.data([1,2,3,2,4,5]).findByValue(2).result();
console.log(dataset);
//Returns [2,2];

.findByValues([array])

Evaluates the dataset to find everything equal to any value in the array.

Example:

var dataset = t.data([1,2,3,2,4,5]).findByValues([2,3,4]).result();
console.log(dataset);
//Returns [2,2,3,4];

.findByKey([int|string])

Evaluates the dataset to find everything that has that key

Example:

var kd = [
  { "key": 1 },
  { "notKey": 2 },
  { "notKey2": 3 },
  { "key": 4 }
]

var dataset = t.data(kd).findByKey("key").result();
console.log(dataset);
//Returns [
  { "key": 1 },
  { "key": 4 }
];

.findByKeys([int|string])

Evaluates the dataset to find everything that has that key

Example:

var kd = [
  { "key": 1 },
  { "notKey": 2 },
  { "notKey2": 3 },
  { "key": 4 },
  { "key2": 9001 }
]

var dataset = t.data(kd).findByKeys(["key", "key2"]).result();
console.log(dataset);
//Returns [
  { "key": 1 },
  { "key": 4 },
  { "key2": 9001}
];

.sortObjKeys([ASC,DESC])

Sorts all the keys in an object.

Example:

var obj = {"b": 1, "a": 2, "c": 3};

var sorted = t.data(obj).sortObjKeys("ASC").result();

console.log(obj);
//Returns {
  "c": 2,
  "b": 1,
  "a": 3
}

var sorted = t.data(obj).sortObjKeys("DESC").result();

console.log(obj);
//Returns {
  "a": 2,
  "b": 1,
  "c": 3
}

.sortValues([ASC,DESC])

Sorts all the values in the object.

Example:

var dataset = [2,3,1];

var sorted = t.data(obj).sortValues("ASC").result();

console.log(obj);
//Returns [3,2,1]

var sorted = t.data(obj).sortValues("DESC").result();

console.log(obj);
//Returns [1,2,3]

.sortByKey([ASC,DESC], key)

Evaluates sorts all the keys in the object.

Example:

var dataset = [
  {
    "key": 5,
  },
  {
    "key": 2
  },
  {
    "key": 1
  }
];

var sorted = t.data(obj).sortByKey("ASC", "key").result();

console.log(obj);
//Returns
[
  {key: 5}, {key: 2}, {key: 1}
]

var sorted = t.data(obj).sortByKey("DESC", "key").result();

console.log(obj);
//Returns
[
  {key: 1}, {key: 2}, {key: 5}
]
