Collection

includes

Checks if value is in collection.

Js.svg
// for string, it checks for a substring of value
if (_.includes('abcd', 'bc')) { }
// true

String

replace

Replace pattern match with replacement.

Js.svg
// only the first match is replaced
const result = _.replace('A.B.C', '.', '_');
// A_B.C

// with a regex with 'g', all the matches are replaced
const result = _.replace('A.B.C', /\w/g, '_');
// _._._

Object

forOwn

Iterates over own enumerable string keyed properties of an object.

Js.svg
let json = {
    "A": "1",
    "B": "2",
    "C": {
        "C1": "3",
        "C2": "4"
    },
    "D": [ "5", "6" ]
};

_.forOwn(json, (value, key) => {
    console.log(`key: ${key} - value: ${value}`);
});
// key: A - value: 1
// key: B - value: 2
// key: C - value: [object Object]
// key: D - value: 5,6
