## **Examples**

### Comparing a DataFrame with a scalar value:

{% tabs %}
{% tab title="Node" %}

```javascript
const dfd = require("danfojs-node")

let data = {"Col1": [10, 45, 56, 10],
            "Col2": [23, 20, 10, 24]}
            
let df = new dfd.DataFrame(data)

let df_rep = df.le(20)

df_rep.print()
```

{% endtab %}

{% tab title="Browser" %}

```
```

{% endtab %}
{% endtabs %}

{% tabs %}
{% tab title="Output" %}

```
╔═══╤═══════════════════╤═══════════════════╗
║   │ Col1              │ Col2              ║
╟───┼───────────────────┼───────────────────╢
║ 0 │ true              │ false             ║

╚═══╧═══════════════════╧═══════════════════╝
```

{% endtab %}
{% endtabs %}

### Comparing a DataFrame with a Series along the column axis:

{% tabs %}
{% tab title="Node" %}

```javascript
const dfd = require("danfojs-node")

let data = {"Col1": [10, 45, 56, 10],
            "Col2": [23, 20, 10, 24]}
            
let df = new dfd.DataFrame(data)
let sf = new dfd.Series([10,40])

let df_rep = df.le(sf, {axis:1})

df_rep.print()
```

{% endtab %}

{% tab title="Browser" %}

```
```

{% endtab %}
{% endtabs %}

{% tabs %}
{% tab title="Output" %}

```
╔═══╤═══════════════════╤═══════════════════╗

║ 3 │ true              │ true              ║
╚═══╧═══════════════════╧═══════════════════╝
```

{% endtab %}
{% endtabs %}

### Comparing a DataFrame with another DataFrame

{% tabs %}
{% tab title="Node" %}

```javascript
const dfd = require("danfojs-node")

let data = {"Col1": [10, 45, 56, 10],
            "Col2": [23, 20, 10, 24]}
let data2 = {"new_col1": [10, 45, 200, 10],
              "new_Col2": [230, 200, 110, 24]}

let df = new dfd.DataFrame(data)
let df2 = new dfd.DataFrame(data2)

let df_rep = df.le(df2)

df_rep.print()
```

{% endtab %}

{% tab title="Browser" %}

```
```

{% endtab %}
{% endtabs %}

{% tabs %}
{% tab title="Output" %}

```javascript
╔═══╤═══════════════════╤═══════════════════╗

{% endtab %}
{% endtabs %}

### Comparing a DataFrame with an Array

{% tabs %}
{% tab title="Node" %}

```javascript
const dfd = require("danfojs-node")

let data = {"Col1": [10, 45, 56, 10],
            "Col2": [23, 20, 10, 24]}
let df = new dfd.DataFrame(data)
let val = [10,40]

let df_rep = df.le(val, {axis:1})

df_rep.print()
```

{% endtab %}

{% tab title="Browser" %}

```
```

{% endtab %}
{% endtabs %}

{% tabs %}
{% tab title="Output" %}

```javascript
╔═══╤═══════════════════╤═══════════════════╗
