refers to the type of the properties in the being processed by a function.
prop()
Fetches a property from an object.
- Type
Overload 1
Overload 2
- Details
Fetches a property or a nested property using either a single property name or an array representing a path.
- Example
// Overload 1
prop('homo', { homo: 114514 }); // 114514
// Overload 2
prop(['inside', 'homo'], { inside: { homo: 114514 } }); // 114514// Overload 1
prop('homo', { homo: 114514 }); // 114514
// Overload 2
prop(['inside', 'homo'], { inside: { homo: 114514 } }); // 114514assoc()
Modifies a property in an object without mutating the original object.
- Type
Overload 1
Overload 2
- Details
Associates a new value to a property or a nested property in the object, returning a new object.
- Example
// Overload 1
assoc('homo', 'yeah', { homo: 114514 }); // { "homo": "yeah" }
// Overload 2
assoc(['inside', 'homo'], 'yeah', { inside: { homo: 114514 } }); // { "inside": { "homo": "yeah" } }// Overload 1
assoc('homo', 'yeah', { homo: 114514 }); // { "homo": "yeah" }
// Overload 2
assoc(['inside', 'homo'], 'yeah', { inside: { homo: 114514 } }); // { "inside": { "homo": "yeah" } }modify()
Applies a function to a property in an object.
- Type
Overload 1
Overload 2
- Details
Modifies a property or a nested property in an object by applying a function to it.
- Example
// Overload 1
modify('homo', (v) => 'yeah', { homo: 114514 }); // { "homo": "yeah" }
// Overload 2
modify(['inside', 'homo'], (v) => 'yeah', { inside: { homo: 114514 } }); // { "inside": { "homo": "yeah" } }// Overload 1
modify('homo', (v) => 'yeah', { homo: 114514 }); // { "homo": "yeah" }
// Overload 2
modify(['inside', 'homo'], (v) => 'yeah', { inside: { homo: 114514 } }); // { "inside": { "homo": "yeah" } }dissoc()
Removes a property from an object.
- Type
Overload 1
Overload 2
- Details
Deletes a property or a nested property from an object and returns the modified object.
- Example
// Overload 1
dissoc('homo', { homo: 114514 }); // {}
// Overload 2
dissoc(['inside', 'homo'], { inside: { homo: 114514 } }); // { "inside": {} }// Overload 1
dissoc('homo', { homo: 114514 }); // {}
// Overload 2
dissoc(['inside', 'homo'], { inside: { homo: 114514 } }); // { "inside": {} }deepClone()
Creates a deep clone of an object.
- Type
- Details
Returns a deep clone of the given object.
- Example
deepClone({ a: 1, b: 2, c: 3 }); // { a: 1, b: 2, c: 3 }deepClone({ a: 1, b: 2, c: 3 }); // { a: 1, b: 2, c: 3 }keys()
Fetches all the keys of an object.
- Type
- Details
Returns an array of all the keys of the given object.
- Example
keys({ a: 1, b: 2, c: 3 }); // ['a', 'b', 'c']keys({ a: 1, b: 2, c: 3 }); // ['a', 'b', 'c']values()
Fetches all the values of an object.
- Type
- Details
Returns an array of all the values of the given object.
- Example
values
({ a: 1, b: 2, c: 3 }); // [1, 2, 3]values
({ a: 1, b: 2, c: 3 }); // [1, 2, 3]makePair()
Converts an array of tuples into an object.
- Type
- Details
Transforms an array of tuples into an object where the first element of each tuple is a key, and the second element is the corresponding value.
- Example
makePair([
['c', 'm'],
['a', 'e'],
['i', 'o']
]); // { c: "m", a: "e", i: "o" }makePair([
['c', 'm'],
['a', 'e'],
['i', 'o']
]); // { c: "m", a: "e", i: "o" }construct()
Curries a class constructor.
- Type
- Details
Accepts a class and returns a curried constructor function.
- Example
class foo {
constructor(a, b, c) {
//do something...
}
}
construct(foo)(1)(2)(3);class foo {
constructor(a, b, c) {
//do something...
}
}
construct(foo)(1)(2)(3);has()
Checks if a property exists in an object.
- Type
- Details
Checks if a property exists in an object and returns true if it does, otherwise returns false.
- Example
has('homo')({ homo: 1 }); // truehas('homo')({ homo: 1 }); // true
